capabilities of iomap, followed by a more detailed catalog +of the interfaces presented by iomap. +If you change iomap, please update this design document. + +File Range Iterator +=================== + +Definitions +----------- + + * **buffer head**: Shattered remnants of the old buffer cache. + + * ``fsblock``: The block size of a file, also known as ``i_blocksize``. + + * ``i_rwsem``: The VFS ``struct inode`` rwsemaphore. + Processes hold this in shared mode to read file state and contents. + Some filesystems may allow shared mode for writes. + Processes often hold this in exclusive mode to change file state and + contents. + + * ``invalidate_lock``: The pagecache ``struct address_space`` + rwsemaphore that protects against folio insertion and removal for + filesystems that support punching out folios below EOF. + Processes wishing to insert folios must hold this lock in shared + mode to prevent removal, though concurrent insertion is allowed. + Processes wishing to remove folios must hold this lock in exclusive + mode to prevent insertions. + Concurrent removals are not allowed. + + * ``dax_read_lock``: The RCU read lock that dax takes to prevent a + device pre-shutdown hook from returning before other threads have + released resources. + + * **filesystem mapping lock**: This synchronization primitive is + internal to the filesystem and must protect the file mapping data + from updates while a mapping is being sampled. + The filesystem author must determine how this coordination should + happen; it does not need to be an actual lock. + + * **iomap internal operation lock**: This is a general term for + synchronization primitives that iomap functions take while holding a + mapping. + A specific example would be taking the folio lock while reading or + writing the pagecache. + + * **pure overwrite**: A write operation that does not require any + metadata or zeroing operations to perform during either submission + or completion. + This implies that the fileystem must have already allocated space + on disk as ``IOMAP_MAPPED`` and the filesystem must not place any + constaints on IO alignment or size. + The only constraints on I/O alignment are device level (minimum I/O + size and alignment, typically sector size). + +``struct iomap`` +---------------- + +The filesystem communicates to the iomap iterator the mapping of +byte ranges of a file to byte ranges of a storage device with the +structure below: + +.. code-block:: c + + struct iomap { + u64 addr; + loff_t offset; + u64 length; + u16 type; + u16 flags; + struct block_device *bdev; + struct dax_device *dax_dev; + voidw *inline_data; + void *private; + const struct iomap_folio_ops *folio_ops; + u64 validity_cookie; + }; + +The fields are as follows: + + * ``offset`` and ``length`` describe the range of file offsets, in + bytes, covered by this mapping. + These fields must always be set by the filesystem. + + * ``type`` describes the type of the space mapping: + + * **IOMAP_HOLE**: No storage has been allocated. + This type must never be returned in response to an ``IOMAP_WRITE`` + operation because writes must allocate and map space, and return + the mapping. + The ``addr`` field must be set to ``IOMAP_NULL_ADDR``. + iomap does not support writing (whether via pagecache or direct + I/O) to a hole. + + * **IOMAP_DELALLOC**: A promise to allocate space at a later time + ("delayed allocation"). + If the filesystem returns IOMAP_F_NEW here and the write fails, the + ``->iomap_end`` function must delete the reservation. + The ``addr`` field must be set to ``IOMAP_NULL_ADDR``. + + * **IOMAP_MAPPED**: The file range maps to specific space on the + storage device. + The device is returned in ``bdev`` or ``dax_dev``. + The device address, in bytes, is returned via ``addr``. + + * **IOMAP_UNWRITTEN**: The file range maps to specific space on the + storage device, but the space has not yet been initialized. + The device is returned in ``bdev`` or ``dax_dev``. + The device address, in bytes, is returned via ``addr``. + Reads from this type of mapping will return zeroes to the caller. + For a write or writeback operation, the ioend should update the + mapping to MAPPED. + Refer to the sections about ioends for more details. + + * **IOMAP_INLINE**: The file range maps to the memory buffer + specified by ``inline_data``. + For write operation, the ``->iomap_end`` function presumably + handles persisting the data. + The ``addr`` field must be set to ``IOMAP_NULL_ADDR``. + + * ``flags`` describe the status of the space mapping. + These flags should be set by the filesystem in ``->iomap_begin``: + + * **IOMAP_F_NEW**: The space under the mapping is newly allocated. + Areas that will not be written to must be zeroed. + If a write fails and the mapping is a space reservation, the + reservation must be deleted. + + * **IOMAP_F_DIRTY**: The inode will have uncommitted metadata needed + to access any data written. + fdatasync is required to commit these changes to persistent + storage. + This needs to take into account metadata changes that *may* be made + at I/O completion, such as file size updates from direct I/O. + + * **IOMAP_F_SHARED**: The space under the mapping is shared. + Copy on write is necessary to avoid corrupting other file data. + + * **IOMAP_F_BUFFER_HEAD**: This mapping requires the use of buffer + heads for pagecache operations. + Do not add more uses of this. + + * **IOMAP_F_MERGED**: Multiple contiguous block mappings were + coalesced into this single mapping. + This is only useful for FIEMAP. + + * **IOMAP_F_XATTR**: The mapping is for extended attribute data, not + regular file data. + This is only useful for FIEMAP. + + * **IOMAP_F_PRIVATE**: Starting with this value, the upper bits can + be set by the filesystem for its own purposes. + + These flags can be set by iomap itself during file operations. + The filesystem should supply an ``->iomap_end`` function if it needs + to observe these flags: + + * **IOMAP_F_SIZE_CHANGED**: The file size has changed as a result of + using this mapping. + + * **IOMAP_F_STALE**: The mapping was found to be stale. + iomap will call ``->iomap_end`` on this mapping and then + ``->iomap_begin`` to obtain a new mapping. + + Currently, these flags are only set by pagecache operations. + + * ``addr`` describes the device address, in bytes. + + * ``bdev`` describes the block device for this mapping. + This only needs to be set for mapped or unwritten operations. + + * ``dax_dev`` describes the DAX device for this mapping. + This only needs to be set for mapped or unwritten operations, and + only for a fsdax operation. + + * ``inline_data`` points to a memory buffer for I/O involving + ``IOMAP_INLINE`` mappings. + This value is ignored for all other mapping types. + + * ``private`` is a pointer to `filesystem-private information + <https://lore.kernel.org/all/[email protected]/>`_. + This value will be passed unchanged to ``->iomap_end``. + + * ``folio_ops`` will be covered in the section on pagecache operations. + + * ``validity_cookie`` is a magic freshness value set by the filesystem + that should be used to detect stale mappings. + For pagecache operations this is critical for correct operation + because page faults can occur, which implies that filesystem locks + should not be held between ``->iomap_begin`` and ``->iomap_end``. + Filesystems with completely static mappings need not set this value. + Only pagecache operations revalidate mappings; see the section about + ``iomap_valid`` for details. + +``struct iomap_ops`` +-------------------- + +Every iomap function requires the filesystem to pass an operations +structure to obtain a mapping and (optionally) to release the mapping: + +.. code-block:: c + + struct iomap_ops { + int (*iomap_begin)(struct inode *inode, loff_t pos, loff_t length, + unsigned flags, struct iomap *iomap, + struct iomap *srcmap); + + int (*iomap_end)(struct inode *inode, loff_t pos, loff_t length, + ssize_t written, unsigned flags, + struct iomap *iomap); + }; + +``->iomap_begin`` +~~~~~~~~~~~~~~~~~ + +iomap operations call ``->iomap_begin`` to obtain one file mapping for +the range of bytes specified by ``pos`` and ``length`` for the file +``inode``. +This mapping should be returned through the ``iomap`` pointer. +The mapping must cover at least the first byte of the supplied file +range, but it does not need to cover the entire requested range. + +Each iomap operation describes the requested operation through the +``flags`` argument. +The exact value of ``flags`` will be documented in the +operation-specific sections below. +These flags can, at least in principle, apply generally to iomap +operations: + + * ``IOMAP_DIRECT`` is set when the caller wishes to issue file I/O to + block storage. + + * ``IOMAP_DAX`` is set when the caller wishes to issue file I/O to + memory-like storage. + + * ``IOMAP_NOWAIT`` is set when the caller wishes to perform a best + effort attempt to avoid any operation that would result in blocking + the submitting task. + This is similar in intent to ``O_NONBLOCK`` for network APIs - it is + intended for asynchronous applications to keep doing other work + instead of waiting for the specific unavailable filesystem resource + to become available. + Filesystems implementing ``IOMAP_NOWAIT`` semantics need to use + trylock algorithms. + They need to be able to satisfy the entire I/O request range with a + single iomap mapping. + They need to avoid reading or writing metadata synchronously. + They need to avoid blocking memory allocations. + They need to avoid waiting on transaction reservations to allow + modifications to take place. + They probably should not be allocating new space. + And so on. + If there is any doubt in the filesystem developer's mind as to + whether any specific ``IOMAP_NOWAIT`` operation may end up blocking, + then they should return ``-EAGAIN`` as early as possible rather than + start the operation and force the submitting task to block. + ``IOMAP_NOWAIT`` is often set on behalf of ``IOCB_NOWAIT`` or + ``RWF_NOWAIT``. + +If it is necessary to read existing file contents from a `different +<https://lore.kernel.org/all/[email protected]/>`_ +device or address range on a device, the filesystem should return that +information via ``srcmap``. +Only pagecache and fsdax operations support reading from one mapping and +writing to another. + +``->iomap_end`` +~~~~~~~~~~~~~~~ + +After the operation completes, the ``->iomap_end`` function, if present, +is called to signal that iomap is finished with a mapping. +Typically, implementations will use this function to tear down any +context that were set up in ``->iomap_begin``. +For example, a write might wish to commit the reservations for the bytes +that were operated upon and unreserve any space that was not operated +upon. +``written`` might be zero if no bytes were touched. +``flags`` will contain the same value passed to ``->iomap_begin``. +iomap ops for reads are not likely to need to supply this function. + +Both functions should return a negative errno code on error, or zero on +success. + +Preparing for File Operations +============================= + +iomap only handles mapping and I/O. +Filesystems must still call out to the VFS to check input parameters +and file state before initiating an I/O operation. +It does not handle obtaining filesystem freeze protection, updating of +timestamps, stripping privileges, or access control. + +Locking Hierarchy +================= + +iomap requires that filesystems supply their own locking model. +There are three categories of synchronization primitives, as far as +iomap is concerned: + + * The **upper** level primitive is provided by the filesystem to + coordinate access to different iomap operations. + The exact primitive is specifc to the filesystem and operation, + but is often a VFS inode, pagecache invalidation, or folio lock. + For example, a filesystem might take ``i_rwsem`` before calling + ``iomap_file_buffered_write`` and ``iomap_file_unshare`` to prevent + these two file operations from clobbering each other. + Pagecache writeback may lock a folio to prevent other threads from + accessing the folio until writeback is underway. + + * The **lower** level primitive is taken by the filesystem in the + ``->iomap_begin`` and ``->iomap_end`` functions to coordinate + access to the file space mapping information. + The fields of the iomap object should be filled out while holding + this primitive. + The upper level synchronization primitive, if any, remains held + while acquiring the lower level synchronization primitive. + For example, XFS takes ``ILOCK_EXCL`` and ext4 takes ``i_data_sem`` + while sampling mappings. + Filesystems with immutable mapping information may not require + synchronization here. + + * The **operation** primitive is taken by an iomap operation to + coordinate access to its own internal data structures. + The upper level synchronization primitive, if any, remains held + while acquiring this primitive. + The lower level primitive is not held while acquiring this + primitive. + For example, pagecache write operations will obtain a file mapping, + then grab and lock a folio to copy new contents. + It may also lock an internal folio state object to update metadata. + +The exact locking requirements are specific to the filesystem; for +certain operations, some of these locks can be elided. +All further mention of locking are *recommendations*, not mandates. +Each filesystem author must figure out the locking for themself. + +Bugs and Limitations +==================== + + * No support for fscrypt. + * No support for compression. + * No support for fsverity yet. + * Strong assumptions that IO should work the way it does on XFS. + * Does iomap *actually* work for non-regular file data? + +Patches welcome! diff --git a/Documentation/filesystems/iomap/index.rst b/Documentation/filesystems/iomap/index.rst new file mode 100644 index 000000000000..3c6a52440250 --- /dev/null

bleed colors in diff. + Heading decorations are documented in sphinx.rst. + +========================= +Supported File Operations +========================= + +.. contents:: Table of Contents + :local: + +Below are a discussion of the high level file operations that iomap +implements. + +Buffered I/O +============ + +Buffered I/O is the default file I/O path in Linux. +File contents are cached in memory ("pagecache") to satisfy reads and +writes. +Dirty cache will be written back to disk at some point that can be +forced via ``fsync`` and variants. + +iomap implements nearly all the folio and pagecache management that +filesystems have to implement themselves under the legacy I/O model. +This means that the filesystem need not know the details of allocating, +mapping, managing uptodate and dirty state, or writeback of pagecache +folios. +Under the legacy I/O model, this was managed very inefficiently with +linked lists of buffer heads instead of the per-folio bitmaps that iomap +uses. +Unless the filesystem explicitly opts in to buffer heads, they will not +be used, which makes buffered I/O much more efficient, and the pagecache +maintainer much happier. + +``struct address_space_operations`` +----------------------------------- + +The following iomap functions can be referenced directly from the +address space operations structure: + + * ``iomap_dirty_folio`` + * ``iomap_release_folio`` + * ``iomap_invalidate_folio`` + * ``iomap_is_partially_uptodate`` + +The following address space operations can be wrapped easily: + + * ``read_folio`` + * ``readahead`` + * ``writepages`` + * ``bmap`` + * ``swap_activate`` + +``struct iomap_folio_ops`` +-------------------------- + +The ``->iomap_begin`` function for pagecache operations may set the +``struct iomap::folio_ops`` field to an ops structure to override +default behaviors of iomap: + +.. code-block:: c + + struct iomap_folio_ops { + struct folio *(*get_folio)(struct iomap_iter *iter, loff_t pos, + unsigned len); + void (*put_folio)(struct inode *inode, loff_t pos, unsigned copied, + struct folio *folio); + bool (*iomap_valid)(struct inode *inode, const struct iomap *iomap); + }; + +iomap calls these functions: + + - ``get_folio``: Called to allocate and return an active reference to + a locked folio prior to starting a write. + If this function is not provided, iomap will call + ``iomap_get_folio``. + This could be used to `set up per-folio filesystem state + <https://lore.kernel.org/all/[email protected]/>`_ + for a write. + + - ``put_folio``: Called to unlock and put a folio after a pagecache + operation completes. + If this function is not provided, iomap will ``folio_unlock`` and + ``folio_put`` on its own. + This could be used to `commit per-folio filesystem state + <https://lore.kernel.org/all/[email protected]/>`_ + that was set up by ``->get_folio``. + + - ``iomap_valid``: The filesystem may not hold locks between + ``->iomap_begin`` and ``->iomap_end`` because pagecache operations + can take folio locks, fault on userspace pages, initiate writeback + for memory reclamation, or engage in other time-consuming actions. + If a file's space mapping data are mutable, it is possible that the + mapping for a particular pagecache folio can `change in the time it + takes + <https://lore.kernel.org/all/[email protected]/>`_ + to allocate, install, and lock that folio. + + For the pagecache, races can happen if writeback doesn't take + ``i_rwsem`` or ``invalidate_lock`` and updates mapping information. + Races can also happen if the filesytem allows concurrent writes. + For such files, the mapping *must* be revalidated after the folio + lock has been taken so that iomap can manage the folio correctly. + + fsdax does not need this revalidation because there's no writeback + and no support for unwritten extents. + + Filesystems subject to this kind of race must provide a + ``->iomap_valid`` function to decide if the mapping is still valid. + If the mapping is not valid, the mapping will be sampled again. + + To support making the validity decision, the filesystem's + ``->iomap_begin`` function may set ``struct iomap::validity_cookie`` + at the same time that it populates the other iomap fields. + A simple validation cookie implementation is a sequence counter. + If the filesystem bumps the sequence counter every time it modifies + the inode's extent map, it can be placed in the ``struct + iomap::validity_cookie`` during ``->iomap_begin``. + If the value in the cookie is found to be different to the value + the filesystem holds when the mapping is passed back to + ``->iomap_valid``, then the iomap should considered stale and the + validation failed. + +These ``struct kiocb`` flags are significant for buffered I/O with iomap: + + * ``IOCB_NOWAIT``: Turns on ``IOMAP_NOWAIT``. + +Internal per-Folio State +------------------------ + +If the fsblock size matches the size of a pagecache folio, it is assumed +that all disk I/O operations will operate on the entire folio. +The uptodate (memory contents are at least as new as what's on disk) and +dirty (memory contents are newer than what's on disk) status of the +folio are all that's needed for this case. + +If the fsblock size is less than the size of a pagecache folio, iomap +tracks the per-fsblock uptodate and dirty state itself. +This enables iomap to handle both "bs < ps" `filesystems +<https://lore.kernel.org/all/[email protected]/>`_ +and large folios in the pagecache. + +iomap internally tracks two state bits per fsblock: + + * ``uptodate``: iomap will try to keep folios fully up to date. + If there are read(ahead) errors, those fsblocks will not be marked + uptodate. + The folio itself will be marked uptodate when all fsblocks within the + folio are uptodate. + + * ``dirty``: iomap will set the per-block dirty state when programs + write to the file. + The folio itself will be marked dirty when any fsblock within the + folio is dirty. + +iomap also tracks the amount of read and write disk IOs that are in +flight. +This structure is much lighter weight than ``struct buffer_head`` +because there is only one per folio, and the per-fsblock overhead is two +bits vs. 104 bytes. + +Filesystems wishing to turn on large folios in the pagecache should call +``mapping_set_large_folios`` when initializing the incore inode. + +Buffered Readahead and Reads +---------------------------- + +The ``iomap_readahead`` function initiates readahead to the pagecache. +The ``iomap_read_folio`` function reads one folio's worth of data into +the pagecache. +The ``flags`` argument to ``->iomap_begin`` will be set to zero. +The pagecache takes whatever locks it needs before calling the +filesystem. + +Buffered Writes +--------------- + +The ``iomap_file_buffered_write`` function writes an ``iocb`` to the +pagecache. +``IOMAP_WRITE`` or ``IOMAP_WRITE`` | ``IOMAP_NOWAIT`` will be passed as +the ``flags`` argument to ``->iomap_begin``. +Callers commonly take ``i_rwsem`` in either shared or exclusive mode +before calling this function. + +mmap Write Faults +~~~~~~~~~~~~~~~~~ + +The ``iomap_page_mkwrite`` function handles a write fault to a folio in +the pagecache. +``IOMAP_WRITE | IOMAP_FAULT`` will be passed as the ``flags`` argument +to ``->iomap_begin``. +Callers commonly take the mmap ``invalidate_lock`` in shared or +exclusive mode before calling this function. + +Buffered Write Failures +~~~~~~~~~~~~~~~~~~~~~~~ + +After a short write to the pagecache, the areas not written will not +become marked dirty. +The filesystem must arrange to `cancel +<https://lore.kernel.org/all/[email protected]/>`_ +such `reservations +<https://lore.kernel.org/linux-xfs/[email protected]/>`_ +because writeback will not consume the reservation. +The ``iomap_file_buffered_write_punch_delalloc`` can be called from a +``->iomap_end`` function to find all the clean areas of the folios +caching a fresh (``IOMAP_F_NEW``) delalloc mapping. +It takes the ``invalidate_lock``. + +The filesystem must supply a function ``punch`` to be called for +each file range in this state. +This function must *only* remove delayed allocation reservations, in +case another thread racing with the current thread writes successfully +to the same region and triggers writeback to flush the dirty data out to +disk. + +Zeroing for File Operations +~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Filesystems can call ``iomap_zero_range`` to perform zeroing of the +pagecache for non-truncation file operations that are not aligned to +the fsblock size. +``IOMAP_ZERO`` will be passed as the ``flags`` argument to +``->iomap_begin``. +Callers typically hold ``i_rwsem`` and ``invalidate_lock`` in exclusive +mode before calling this function. + +Unsharing Reflinked File Data +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Filesystems can call ``iomap_file_unshare`` to force a file sharing +storage with another file to preemptively copy the shared data to newly +allocate storage. +``IOMAP_WRITE | IOMAP_UNSHARE`` will be passed as the ``flags`` argument +to ``->iomap_begin``. +Callers typically hold ``i_rwsem`` and ``invalidate_lock`` in exclusive +mode before calling this function. + +Truncation +---------- + +Filesystems can call ``iomap_truncate_page`` to zero the bytes in the +pagecache from EOF to the end of the fsblock during a file truncation +operation. +``truncate_setsize`` or ``truncate_pagecache`` will take care of +everything after the EOF block. +``IOMAP_ZERO`` will be passed as the ``flags`` argument to +``->iomap_begin``. +Callers typically hold ``i_rwsem`` and ``invalidate_lock`` in exclusive +mode before calling this function. + +Pagecache Writeback +------------------- + +Filesystems can call ``iomap_writepages`` to respond to a request to +write dirty pagecache folios to disk. +The ``mapping`` and ``wbc`` parameters should be passed unchanged. +The ``wpc`` pointer should be allocated by the filesystem and must +be initialized to zero. + +The pagecache will lock each folio before trying to schedule it for +writeback. +It does not lock ``i_rwsem`` or ``invalidate_lock``. + +The dirty bit will be cleared for all folios run through the +``->map_blocks`` machinery described below even if the writeback fails. +This is to prevent dirty folio clots when storage devices fail; an +``-EIO`` is recorded for userspace to collect via ``fsync``. + +The ``ops`` structure must be specified and is as follows: + +``struct iomap_writeback_ops`` +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +.. code-block:: c + + struct iomap_writeback_ops { + int (*map_blocks)(struct iomap_writepage_ctx *wpc, struct inode *inode, + loff_t offset, unsigned len); + int (*prepare_ioend)(struct iomap_ioend *ioend, int status); + void (*discard_folio)(struct folio *folio, loff_t pos); + }; + +The fields are as follows: + + - ``map_blocks``: Sets ``wpc->iomap`` to the space mapping of the file + range (in bytes) given by ``offset`` and ``len``. + iomap calls this function for each dirty fs block in each dirty folio, + though it will `reuse mappings + <https://lore.kernel.org/all/[email protected]/>`_ + for runs of contiguous dirty fsblocks within a folio. + Do not return ``IOMAP_INLINE`` mappings here; the ``->iomap_end`` + function must deal with persisting written data. + Do not return ``IOMAP_DELALLOC`` mappings here; iomap currently + requires mapping to allocated space. + Filesystems can skip a potentially expensive mapping lookup if the + mappings have not changed. + This revalidation must be open-coded by the filesystem; it is + unclear if ``iomap::validity_cookie`` can be reused for this + purpose. + This function must be supplied by the filesystem. + + - ``prepare_ioend``: Enables filesystems to transform the writeback + ioend or perform any other preparatory work before the writeback I/O + is submitted. + This might include pre-write space accounting updates, or installing + a custom ``->bi_end_io`` function for internal purposes, such as + deferring the ioend completion to a workqueue to run metadata update + transactions from process context. + This function is optional. + + - ``discard_folio``: iomap calls this function after ``->map_blocks`` + fails to schedule I/O for any part of a dirty folio. + The function should throw away any reservations that may have been + made for the write. + The folio will be marked clean and an ``-EIO`` recorded in the + pagecache. + Filesystems can use this callback to `remove + <https://lore.kernel.org/all/[email protected]/>`_ + delalloc reservations to avoid having delalloc reservations for + clean pagecache. + This function is optional. + +Pagecache Writeback Completion +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +To handle the bookkeeping that must happen after disk I/O for writeback +completes, iomap creates chains of ``struct iomap_ioend`` objects that +wrap the ``bio`` that is used to write pagecache data to disk. +By default, iomap finishes writeback ioends by clearing the writeback +bit on the folios attached to the ``ioend``. +If the write failed, it will also set the error bits on the folios and +the address space. +This can happen in interrupt or process context, depending on the +storage device. + +Filesystems that need to update internal bookkeeping (e.g. unwritten +extent conversions) should provide a ``->prepare_ioend`` function to +set ``struct iomap_end::bio::bi_end_io`` to its own function. +This function should call ``iomap_finish_ioends`` after finishing its +own work (e.g. unwritten extent conversion). + +Some filesystems may wish to `amortize the cost of running metadata +transactions +<https://lore.kernel.org/all/[email protected]/>`_ +for post-writeback updates by batching them. +They may also require transactions to run from process context, which +implies punting batches to a workqueue. +iomap ioends contain a ``list_head`` to enable batching. + +Given a batch of ioends, iomap has a few helpers to assist with +amortization: + + * ``iomap_sort_ioends``: Sort all the ioends in the list by file + offset. + + * ``iomap_ioend_try_merge``: Given an ioend that is not in any list and + a separate list of sorted ioends, merge as many of the ioends from + the head of the list into the given ioend. + ioends can only be merged if the file range and storage addresses are + contiguous; the unwritten and shared status are the same; and the + write I/O outcome is the same. + The merged ioends become their own list. + + * ``iomap_finish_ioends``: Finish an ioend that possibly has other + ioends linked to it. + +Direct I/O +========== + +In Linux, direct I/O is defined as file I/O that is issued directly to +storage, bypassing the pagecache. +The ``iomap_dio_rw`` function implements O_DIRECT (direct I/O) reads and +writes for files. + +.. code-block:: c + + ssize_t iomap_dio_rw(struct kiocb *iocb, struct iov_iter *iter, + const struct iomap_ops *ops, + const struct iomap_dio_ops *dops, + unsigned int dio_flags, void *private, + size_t done_before); + +The filesystem can provide the ``dops`` parameter if it needs to perform +extra work before or after the I/O is issued to storage. +The ``done_before`` parameter tells the how much of the request has +already been transferred. +It is used to continue a request asynchronously when `part of the +request +<https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c03098d4b9ad76bca2966a8769dcfe59f7f85103>`_ +has already been completed synchronously. + +The ``done_before`` parameter should be set if writes for the ``iocb`` +have been initiated prior to the call. +The direction of the I/O is determined from the ``iocb`` passed in. + +The ``dio_flags`` argument can be set to any combination of the +following values: + + * ``IOMAP_DIO_FORCE_WAIT``: Wait for the I/O to complete even if the + kiocb is not synchronous. + + * ``IOMAP_DIO_OVERWRITE_ONLY``: Perform a pure overwrite for this range + or fail with ``-EAGAIN``. + This can be used by filesystems with complex unaligned I/O + write paths to provide an optimised fast path for unaligned writes. + If a pure overwrite can be performed, then serialisation against + other I/Os to the same filesystem block(s) is unnecessary as there is + no risk of stale data exposure or data loss. + If a pure overwrite cannot be performed, then the filesystem can + perform the serialisation steps needed to provide exclusive access + to the unaligned I/O range so that it can perform allocation and + sub-block zeroing safely. + Filesystems can use this flag to try to reduce locking contention, + but a lot of `detailed checking + <https://lore.kernel.org/linux-ext4/[email protected]/>`_ + is required to do it `correctly + <https://lore.kernel.org/linux-ext4/[email protected]/>`_. + + * ``IOMAP_DIO_PARTIAL``: If a page fault occurs, return whatever + progress has already been made. + The caller may deal with the page fault and retry the operation. + If the caller decides to retry the operation, it should pass the + accumulated return values of all previous calls as the + ``done_before`` parameter to the next call. + +These ``struct kiocb`` flags are significant for direct I/O with iomap: + + * ``IOCB_NOWAIT``: Turns on ``IOMAP_NOWAIT``. + + * ``IOCB_SYNC``: Ensure that the device has persisted data to disk + before completing the call. + In the case of pure overwrites, the I/O may be issued with FUA + enabled. + + * ``IOCB_HIPRI``: Poll for I/O completion instead of waiting for an + interrupt. + Only meaningful for asynchronous I/O, and only if the entire I/O can + be issued as a single ``struct bio``. + + * ``IOCB_DIO_CALLER_COMP``: Try to run I/O completion from the caller's + process context. + See ``linux/fs.h`` for more details. + +Filesystems should call ``iomap_dio_rw`` from ``->read_iter`` and +``->write_iter``, and set ``FMODE_CAN_ODIRECT`` in the ``->open`` +function for the file. +They should not set ``->direct_IO``, which is deprecated. + +If a filesystem wishes to perform its own work before direct I/O +completion, it should call ``__iomap_dio_rw``. +If its return value is not an error pointer or a NULL pointer, the +filesystem should pass the return value to ``iomap_dio_complete`` after +finishing its internal work. + +Return Values +------------- + +``iomap_dio_rw`` can return one of the following: + + * A non-negative number of bytes transferred. + + * ``-ENOTBLK``: Fall back to buffered I/O. + iomap itself will return this value if it cannot invalidate the page + cache before issuing the I/O to storage. + The ``->iomap_begin`` or ``->iomap_end`` functions may also return + this value. + + * ``-EIOCBQUEUED``: The asynchronous direct I/O request has been + queued and will be completed separately. + + * Any of the other negative error codes. + +Direct Reads +------------ + +A direct I/O read initiates a read I/O from the storage device to the +caller's buffer. +Dirty parts of the pagecache are flushed to storage before initiating +the read

``i_rwsem`` in shared mode before calling this +function. + +Direct Writes +------------- + +A direct I/O write initiates a write I/O to the storage device from the +caller's buffer. +Dirty parts of the pagecache are flushed to storage before initiating +the write io. +The pagecache is invalidated both before and after the write io. +The ``flags`` value for ``->iomap_begin`` will be ``IOMAP_DIRECT | +IOMAP_WRITE`` with any combination of the following enhancements: + + * ``IOMAP_NOWAIT``, as defined previously. + + * ``IOMAP_OVERWRITE_ONLY``: Allocating blocks and zeroing partial + blocks is not allowed. + The entire file range must map to a single written or unwritten + extent. + The file I/O range must be aligned to the filesystem block size + if the mapping is unwritten and the filesystem cannot handle zeroing + the unaligned regions without exposing stale contents. + +Callers commonly hold ``i_rwsem`` in shared or exclusive mode before +calling this function. + +``struct iomap_dio_ops:`` +------------------------- +.. code-block:: c + + struct iomap_dio_ops { + void (*submit_io)(const struct iomap_iter *iter, struct bio *bio, + loff_t file_offset); + int (*end_io)(struct kiocb *iocb, ssize_t size, int error, + unsigned flags); + struct bio_set *bio_set; + }; + +The fields of this structure are as follows: + + - ``submit_io``: iomap calls this function when it has constructed a + ``struct bio`` object for the I/O requested, and wishes to submit it + to the block device. + If no function is provided, ``submit_bio`` will be called directly. + Filesystems that would like to perform additional work before (e.g. + data replication for btrfs) should implement this function. + + - ``end_io``: This is called after the ``struct bio`` completes. + This function should perform post-write conversions of unwritten + extent mappings, handle write failures, etc. + The ``flags`` argument may be set to a combination of the following: + + * ``IOMAP_DIO_UNWRITTEN``: The mapping was unwritten, so the ioend + should mark the extent as written. + + * ``IOMAP_DIO_COW``: Writing to the space in the mapping required a + copy on write operation, so the ioend should switch mappings. + + - ``bio_set``: This allows the filesystem to provide a custom bio_set + for allocating direct I/O bios. + This enables filesystems to `stash additional per-bio information + <https://lore.kernel.org/all/[email protected]/>`_ + for private use. + If this field is NULL, generic ``struct bio`` objects will be used. + +Filesystems that want to perform extra work after an I/O completion +should set a custom ``->bi_end_io`` function via ``->submit_io``. +Afterwards, the custom endio function must call +``iomap_dio_bio_end_io`` to finish the direct I/O. + +DAX I/O +======= + +Some storage devices can be directly mapped as memory. +These devices support a new access mode known as "fsdax" that allows +loads and stores through the CPU and memory controller. + +fsdax Reads +----------- + +A fsdax read performs a memcpy from storage device to the caller's +buffer. +The ``flags`` value for ``->iomap_begin`` will be ``IOMAP_DAX`` with any +combination of the following enhancements: + + * ``IOMAP_NOWAIT``, as defined previously. + +Callers commonly hold ``i_rwsem`` in shared mode before calling this +function. + +fsdax Writes +------------ + +A fsdax write initiates a memcpy to the storage device from the caller's +buffer. +The ``flags`` value for ``->iomap_begin`` will be ``IOMAP_DAX | +IOMAP_WRITE`` with any combination of the following enhancements: + + * ``IOMAP_NOWAIT``, as defined previously. + + * ``IOMAP_OVERWRITE_ONLY``: The caller requires a pure overwrite to be + performed from this mapping. + This requires the filesystem extent mapping to already exist as an + ``IOMAP_MAPPED`` type and span the entire range of the write I/O + request. + If the filesystem cannot map this request in a way that allows the + iomap infrastructure to perform a pure overwrite, it must fail the + mapping operation with ``-EAGAIN``. + +Callers commonly hold ``i_rwsem`` in exclusive mode before calling this +function. + +fsdax mmap Faults +~~~~~~~~~~~~~~~~~ + +The ``dax_iomap_fault`` function handles read and write faults to fsdax +storage. +For a read fault, ``IOMAP_DAX | IOMAP_FAULT`` will be passed as the +``flags`` argument to ``->iomap_begin``. +For a write fault, ``IOMAP_DAX | IOMAP_FAULT | IOMAP_WRITE`` will be +passed as the ``flags`` argument to ``->iomap_begin``. + +Callers commonly hold the same locks as they do to call their iomap +pagecache counterparts. + +fsdax Truncation, fallocate, and Unsharing +------------------------------------------ + +For fsdax files, the following functions are provided to replace their +iomap pagecache I/O counterparts. +The ``flags`` argument to ``->iomap_begin`` are the same as the +pagecache counterparts, with ``IOMAP_DAX`` added. + + * ``dax_file_unshare`` + * ``dax_zero_range`` + * ``dax_truncate_page`` + +Callers commonly hold the same locks as they do to call their iomap +pagecache counterparts. + +fsdax Deduplication +------------------- + +Filesystems implementing the ``FIDEDUPERANGE`` ioctl must call the +``dax_remap_file_range_prep`` function with their own iomap read ops. + +Seeking Files +============= + +iomap implements the two iterating whence modes of the ``llseek`` system +call. + +SEEK_DATA +--------- + +The ``iomap_seek_data`` function implements the SEEK_DATA "whence" value +for llseek. +``IOMAP_REPORT`` will be passed as the ``flags`` argument to +``->iomap_begin``. + +For unwritten mappings, the pagecache will be searched. +Regions of the pagecache with a folio mapped and uptodate fsblocks +within those folios will be reported as data areas. + +Callers commonly hold ``i_rwsem`` in shared mode before calling this +function. + +SEEK_HOLE +--------- + +The ``iomap_seek_hole`` function implements the SEEK_HOLE "whence" value +for llseek. +``IOMAP_REPORT`` will be passed as the ``flags`` argument to +``->iomap_begin``. + +For unwritten mappings, the pagecache will be searched. +Regions of the pagecache with no folio mapped, or a !uptodate fsblock +within a folio will be reported as sparse hole areas. + +Callers commonly hold ``i_rwsem`` in shared mode before calling this +function. + +Swap File Activation +==================== + +The ``iomap_swapfile_activate`` function finds all the base-page aligned +regions in a file and sets them up as swap space. +The file will be ``fsync()``'d before activation. +``IOMAP_REPORT`` will be passed as the ``flags`` argument to +``->iomap_begin``. +All mappings must be mapped or unwritten; cannot be dirty or shared, and +cannot span multiple block devices. +Callers must hold ``i_rwsem`` in exclusive mode; this is already +provided by ``swapon``. + +File Space Mapping Reporting +============================ + +iomap implements two of the file space mapping system calls. + +FS_IOC_FIEMAP +------------- + +The ``iomap_fiemap`` function exports file extent mappings to userspace +in the format specified by the ``FS_IOC_FIEMAP`` ioctl. +``IOMAP_REPORT`` will be passed as the ``flags`` argument to +``->iomap_begin``. +Callers commonly hold ``i_rwsem`` in shared mode before calling this +function. + +FIBMAP (deprecated) +------------------- + +``iomap_bmap`` implements FIBMAP. +The calling conventions are the same as for FIEMAP. +This function is only provided to maintain compatibility for filesystems +that implemented FIBMAP prior to conversion. +This ioctl is deprecated; do **not** add a FIBMAP implementation to +filesystems that do not have it. +Callers should probably hold ``i_rwsem`` in shared mode

The classic Linux I/O path is not terribly efficient. + Pagecache operations lock a single base page at a time and then call + into the filesystem to return a mapping for only that page. + Direct I/O operations build I/O requests a single file block at a + time. + This worked well enough for direct/indirect-mapped filesystems such + as ext2, but is very inefficient for extent-based filesystems such + as XFS. + + 2. Large folios are only supported via iomap; there are no plans to + convert the old buffer_head path to use them. + + 3. Direct access to storage on memory-like devices (fsdax) is only + supported via iomap. + + 4. Lower maintenance overhead for individual filesystem maintainers. + iomap handles common pagecache related operations itself, such as + allocating, instantiating, locking, and unlocking of folios. + No ->write_begin(), ->write_end() or direct_IO + address_space_operations are required to be implemented by + filesystem using iomap. + +How Do I Convert a Filesystem? +============================== + +First, add ``#include <linux/iomap.h>`` from your source code and add +``select FS_IOMAP`` to your filesystem's Kconfig option. +Build the kernel, run fstests with the ``-g all`` option across a wide +variety of your filesystem's supported configurations to build a +baseline of which tests pass and which ones fail. + +The recommended approach is first to implement ``->iomap_begin`` (and +``->iomap_end`` if necessary) to allow iomap to obtain a read-only +mapping of a file range. +In most cases, this is a relatively trivial conversion of the existing +``get_block()`` function for read-only mappings. +``FS_IOC_FIEMAP`` is a good first target because it is trivial to +implement support for it and then to determine that the extent map +iteration is correct from userspace. +If FIEMAP is returning the correct information, it's a good sign that +other read-only mapping operations will do the right thing. + +Next, modify the filesystem's ``get_block(create = false)`` +implementation to use the new ``->iomap_begin`` implementation to map +file space for selected read operations. +Hide behind a debugging knob the ability to switch on the iomap mapping +functions for selected call paths. +It is necessary to write some code to fill out the bufferhead-based +mapping information from the ``iomap`` structure, but the new functions +can be tested without needing to implement any iomap APIs. + +Once the read-only functions are working like this, convert each high +level file operation one by one to use iomap native APIs instead of +going through ``get_block()``. +Done one at a time, regressions should be self evident. +You *do* have a regression test baseline for fstests, right? +It is suggested to convert swap file activation, ``SEEK_DATA``, and +``SEEK_HOLE`` before tackling the I/O paths. +A likely complexity at this point will be converting the buffered read +I/O path because of bufferheads. +The buffered read I/O paths doesn't need to be converted yet, though the +direct I/O read path should be converted in this phase. + +At this point, you should look over your ``->iomap_begin`` function. +If it switches between large blocks of code based on dispatching of the +``flags`` argument, you should consider breaking it up into +per-operation iomap ops with smaller, more cohesive functions. +XFS is a good example of this. + +The next thing to do is implement ``get_blocks(create == true)`` +functionality in the ``->iomap_begin``/``->iomap_end`` methods. +It is strongly recommended to create separate mapping functions and +iomap ops for write operations. +Then convert the direct I/O write path to iomap, and start running fsx +w/ DIO enabled in earnest on filesystem. +This will flush out lots of data integrity corner case bugs that the new +write mapping implementation introduces. + +Now, convert any remaining file operations to call the iomap functions. +This will get the entire filesystem using the new mapping functions, and +they should largely be debugged and working correctly after this step. + +Most likely at this point, the buffered read and write paths will still +need to be converted. +The mapping functions should all work correctly, so all that needs to be +done is rewriting all the code that interfaces with bufferheads to +interface with iomap and folios. +It is much easier first to get regular file I/O (without any fancy +features like fscrypt, fsverity, compression, or data=journaling) +converted to use iomap. +Some of those fancy features (fscrypt and compression) aren't +implemented yet in iomap. +For unjournalled filesystems that use the pagecache for symbolic links +and directories, you might also try converting their handling to iomap. + +The rest is left as an exercise for the reader, as it will be different +for every filesystem. +If you encounter problems, email the people and lists in +``get_maintainers.pl`` for help. diff --git a/Documentation/filesystems/mount_api.rst b/Documentation/filesystems/mount_api.rst index 9aaf6ef75eb5..317934c9e8fc 100644 --- a/Documentation/filesystems/mount_api.rst +++ b/Documentation/filesystems/mount_api.rst @@ -645,6 +645,8 @@ The members are as follows: fs_param_is_blockdev Blockdev path * Needs lookup fs_param_is_path Path * Needs lookup fs_param_is_fd File descriptor result->int_32 + fs_param_is_uid User ID (u32) result->uid + fs_param_is_gid Group ID (u32) result->gid ======================= ======================= ===================== Note that if the value is of fs_param_is_bool type, fs_parse() will try @@ -678,6 +680,8 @@ The members are as follows: fsparam_bdev() fs_param_is_blockdev fsparam_path() fs_param_is_path fsparam_fd() fs_param_is_fd + fsparam_uid() fs_param_is_uid + fsparam_gid() fs_param_is_gid ======================= =============================================== all of which take two arguments, name string and option number - for @@ -784,8 +788,9 @@ process the parameters it is given. option number (which it returns).

As a consequence, for any blkg associated with the - * request queue this instance of the scheduler is attached - * to, we are guaranteed that such a blkg is not destroyed, and - * that all the pointers it contains are consistent, while we - * are holding bfqd->lock. A blkg_lookup performed with - * bfqd->lock held then returns a fully consistent blkg, which - * remains consistent until this lock is held. - * - * Thanks to the last fact, and to the fact that: (1) bfqg has - * been obtained through a blkg_lookup in the above - * assignment, and (2) bfqd->lock is being held, here we can - * safely use the policy data for the involved blkg (i.e., the - * field bfqg->pd) to get to the blkg associated with bfqg, - * and then we can safely use any field of blkg. After we - * release bfqd->lock, even just getting blkg through this - * bfqg may cause dangling references to be traversed, as - * bfqg->pd may not exist any more. - * - * In view of the above facts, here we cache, in the bfqg, any - * blkg data we may need for this bic, and for its associated - * bfq_queue. As of now, we need to cache only the path of the - * blkg, which is used in the bfq_log_* functions. - * - * Finally, note that bfqg itself needs to be protected from - * destruction on the blkg_free of the original blkg (which - * invokes bfq_pd_free). We use an additional private - * refcounter for bfqg, to let it disappear only after no - * bfq_queue refers to it any longer. - */ - blkg_path(bfqg_to_blkg(bfqg), bfqg->blkg_path, sizeof(bfqg->blkg_path)); bic->blkcg_serial_nr = serial_nr; } diff --git a/block/bfq-iosched.c b/block/bfq-iosched.c index 4b88a54a9b76..36a4998c4b37 100644 --- a/block/bfq-iosched.c +++ b/block/bfq-iosched.c @@ -5463,40 +5463,42 @@ static void bfq_exit_icq_bfqq(struct bfq_io_cq *bic, bool is_sync, } } +static void _bfq_exit_icq(struct bfq_io_cq *bic, unsigned int num_actuators) +{ + struct bfq_iocq_bfqq_data *bfqq_data = bic->bfqq_data; + unsigned int act_idx; + + for (act_idx = 0; act_idx < num_actuators; act_idx++) { + if (bfqq_data[act_idx].stable_merge_bfqq) + bfq_put_stable_ref(bfqq_data[act_idx].stable_merge_bfqq); + + bfq_exit_icq_bfqq(bic, true, act_idx); + bfq_exit_icq_bfqq(bic, false, act_idx); + } +} + static void bfq_exit_icq(struct io_cq *icq) { struct bfq_io_cq *bic = icq_to_bic(icq); struct bfq_data *bfqd = bic_to_bfqd(bic); unsigned long flags; - unsigned int act_idx; + /* * If bfqd and thus bfqd->num_actuators is not available any * longer, then cycle over all possible per-actuator bfqqs in * next loop.

This module provides types for implementing block drivers that interface the +//! blk-mq subsystem. +//! +//! To implement a block device driver, a Rust module must do the following: +//! +//! - Implement [`Operations`] for a type `T`. +//! - Create a [`TagSet<T>`]. +//! - Create a [`GenDisk<T>`], via the [`GenDiskBuilder`]. +//! - Add the disk to the system by calling [`GenDiskBuilder::build`] passing in +//! the `TagSet` reference. +//! +//! The types available in this module that have direct C counterparts are: +//! +//! - The [`TagSet`] type that abstracts the C type `struct tag_set`. +//! - The [`GenDisk`] type that abstracts the C type `struct gendisk`. +//! - The [`Request`] type that abstracts the C type `struct request`. +//! +//! The kernel will interface with the block device driver by calling the method +//! implementations of the `Operations` trait. +//! +//! IO requests are passed to the driver as [`kernel::types::ARef<Request>`] +//! instances. The `Request` type is a wrapper around the C `struct request`. +//! The driver must mark end of processing by calling one of the +//! `Request::end`, methods. Failure to do so can lead to deadlock or timeout +//! errors. Please note that the C function `blk_mq_start_request` is implicitly +//! called when the request is queued with the driver. +//! +//! The `TagSet` is responsible for creating and maintaining a mapping between +//! `Request`s and integer ids as well as carrying a pointer to the vtable +//! generated by `Operations`. This mapping is useful for associating +//! completions from hardware with the correct `Request` instance. The `TagSet` +//! determines the maximum queue depth by setting the number of `Request` +//! instances available to the driver, and it determines the number of queues to +//! instantiate for the driver. If possible, a driver should allocate one queue +//! per core, to keep queue data local to a core. +//! +//! One `TagSet` instance can be shared between multiple `GenDisk` instances. +//! This can be useful when implementing drivers where one piece of hardware +//! with one set of IO resources are represented to the user as multiple disks. +//! +//! One significant difference between block device drivers implemented with +//! these Rust abstractions and drivers implemented in C, is that the Rust +//! drivers have to own a reference count on the `Request` type when the IO is +//! in flight. This is to ensure that the C `struct request` instances backing +//! the Rust `Request` instances are live while the Rust driver holds a +//! reference to the `Request`. In addition, the conversion of an integer tag to +//! a `Request` via the `TagSet` would not be sound without this bookkeeping. +//! +//! [`GenDisk`]: gen_disk::GenDisk +//!
