We're deleting a root and looking it up by key does not succeed, this
is an inconsistent state and we can't do anything. All callers handle

The unlikely case of lookup error in btrfs_remove_block_group() can be
handled properly, in its caller this would lead to a transaction abort.
We can't do anything else, a block group must have been loaded first.

Turn a BUG_ON to a properly handled error and update the error message
in the caller. It is expected that @em_in and @start passed to
btrfs_add_extent_mapping() overlap. Besides tests, the only caller
btrfs_get_extent() makes sure this is true.

The helper btrfs_may_delete() is a copy of generic fs/namei.c:may_delete()
to verify various conditions before deletion. There's a BUG_ON added
before linux.git started, we can turn it to a proper error handling
at least in our local helper. A mistmatch between directory and the
deleted dentry is clearly invalid.
This won't be probably ever hit due to the way how the parameters are
set from the caller btrfs_ioctl_snap_destroy(), using a VFS helper
lookup_one().

Since we can read/modify the value from the sysfs interface concurrently,
it would be better to protect it from compiler optimizations.
Currently, there is only one read policy BTRFS_READ_POLICY_PID available,
so no actual problem can happen now. This is a preparation for the future
expansion.

When logging an inode and we require to copy items from subvolume leaves
to the log tree, we clone each subvolume leaf and than use that clone to
copy items to the log tree. This is required to avoid possible deadlocks
as stated in commit 796787c978ef ("btrfs: do not modify log tree while
holding a leaf from fs tree locked").
The cloning requires allocating an extent buffer (struct extent_buffer)
and then allocating pages (folios) to attach to the extent buffer. This
may be slow in case we are under memory pressure, and since we are doing
the cloning while holding a read lock on a subvolume leaf, it means we
can be blocking other operations on that leaf for significant periods of
time, which can increase latency on operations like creating other files,
renaming files, etc. Similarly because we're under a log transaction, we
may also cause extra delay on other tasks doing an fsync, because syncing
the log requires waiting for tasks that joined a log transaction to exit
the transaction.
So to improve this, for any inode logging operation that needs to copy
items from a subvolume leaf ("full sync" or "copy everything" bit set
in the inode), preallocate a dummy extent buffer before locking any
extent buffer from the subvolume tree, and even before joining a log
transaction, add it to the log context and then use it when we need to
copy items from a subvolume leaf to the log tree. This avoids making
other operations get extra latency when waiting to lock a subvolume
leaf that is used during inode logging and we are under heavy memory
pressure.
The following test script with bonnie++ was used to test this:

At btrfs_delete_unused_bgs(), the use of the list_is_singular() check on
a block group may not be immediately obvious. It is there to prevent
losing raid profile information for a block group type (data, metadata or
system), as that information is removed from
fs_info->avail_[data|metadata|system]_alloc_bits when the last block group
of a given type is deleted. So deleting the block group would later result
in creating block groups of that type with a single profile (because
fs_info->avail_*_alloc_bits would have a value of 0).
This check was added in commit aefbe9a633b5 ("btrfs: Fix lost-data-profile
caused by auto removing bg").
So add a comment mentioning the need for the check.

Note: this is a fixed version that was previously reverted as
e01a83e12604 ("Revert "btrfs: zstd: fix and simplify the inline extent
decompression""), with fixed parameters to memzero_page().
[BUG]
If we have a filesystem with 4k sectorsize, and an inlined compressed
extent created like this:
item 4 key (257 INODE_ITEM 0) itemoff 15863 itemsize 160
generation 8 transid 8 size 4096 nbytes 4096
block group 0 mode 100600 links 1 uid 0 gid 0 rdev 0
sequence 1 flags 0x0(none)
item 5 key (257 INODE_REF 256) itemoff 15839 itemsize 24
index 2 namelen 14 name: source_inlined
item 6 key (257 EXTENT_DATA 0) itemoff 15770 itemsize 69
generation 8 type 0 (inline)
inline extent data size 48 ram_bytes 4096 compression 3 (zstd)
Then trying to reflink that extent in an aarch64 system with 64K page
size, the reflink would just fail:
# xfs_io -f -c "reflink $mnt/source_inlined 0 60k 4k" $mnt/dest
XFS_IOC_CLONE_RANGE: Input/output error
[CAUSE]
In zstd_decompress(), we didn't treat @start_byte as just a page offset,
but also use it as an indicator on whether we should error out, without
any proper explanation (this is copied from other decompression code).
In reality, for subpage cases, although @start_byte can be non-zero,
we should never switch input/output buffer nor error out, since the whole
input/output buffer should never exceed one sector, thus we should not
need to do any buffer switch.
Thus the current code using @start_byte as a condition to switch
input/output buffer or finish the decompression is completely incorrect.
[FIX]
The fix involves several modification:
- Rename @start_byte to @dest_pgoff to properly express its meaning
- Use @sectorsize other than PAGE_SIZE to properly initialize the
output buffer size
- Use correct destination offset inside the destination page
- Simplify the main loop
Since the input/output buffer should never switch, we only need one
zstd_decompress_stream() call.
- Consider early end as an error
After the fix, even on 64K page sized aarch64, above reflink now
works as expected:
# xfs_io -f -c "reflink $mnt/source_inlined 0 60k 4k" $mnt/dest
linked 4096/4096 bytes at offset 61440
And results the correct file layout:
item 9 key (258 INODE_ITEM 0) itemoff 15542 itemsize 160
generation 10 transid 10 size 65536 nbytes 4096
block group 0 mode 100600 links 1 uid 0 gid 0 rdev 0
sequence 1 flags 0x0(none)
item 10 key (258 INODE_REF 256) itemoff 15528 itemsize 14
index 3 namelen 4 name: dest
item 11 key (258 XATTR_ITEM 3817753667) itemoff 15445 itemsize 83

transid 10 data_len 37 name_len 16
name: security.selinux
data unconfined_u:object_r:unlabeled_t:s0
item 12 key (258 EXTENT_DATA 61440) itemoff 15392 itemsize 53

After the conversion to folio interfaces (but without the patch to
enable larger folio allocation), there is an LTP report about observable
performance drop on metadata heavy operations.
https://lore.kernel.org/linux-btrfs/202312221750.571925bd-oliver.sang@intel.com/
This drop is caused by the extra code of calculating the
folio_size()/folio_shift(), instead of the old hard coded
PAGE_SIZE/PAGE_SHIFT.
To slightly reduce the overhead, just cache both folio_size and
folio_shift in extent_buffer.
The two new members (u32 folio_size and u8 folio_shift) are stored
inside the holes of extent_buffer. folio_size is shared with len, which
is reduced to u32. The size of eb does not change.

- Split data and metadata endio paths
Now for data path we no longer do any verification in

inlined extent, and we already have an ASSERT() and tree-checker, to
make sure we can only get inline extent at file offset 0.
Any invalid inline extent with non-zero file offset would be rejected by
tree-checker in the first place.

In IEEE 1394 Amendment (IEEE 1394a-2000), the short bus reset is added
to resolve the shortcomings of the long bus reset in IEEE 1394-1995.
However, it is well-known that the solution is not necessarily
effective in the mixing environment that both IEEE 1394-1995 PHY and
IEEE 1394a-2000 (or later) PHY exist, as described in section 8.4.6.2

The current implementation of firewire stack schedules the short bus
reset when attempting to resolve the mismatch of gap count in the
certain generation of bus topology. It can cause the continuous bus
reset in the issued environment.
The workaround simply uses the long bus reset instead of the short bus
reset. It is desirable to detect whether the issued environment or
not. However, the way to access PHY registers from remote note is

In commit 19416123ab3e ("block: define 'struct bvec_iter' as packed"),
what we need is to save the 4byte padding, and avoid `bio` to spread on
one extra cache line.
It is enough to define it as '__packed __aligned(4)', as '__packed'
alone means byte aligned, and can cause compiler to generate horrible
code on architectures that don't support unaligned access in case that
bvec_iter is embedded in other structures.

Introduced a stupid bug in commit 782bfd03c3ae ("of: property: Improve
finding the supplier of a remote-endpoint property") due to a last minute
incorrect edit of "index !=0" into "!index". This patch fixes it to be
"index > 0" to match the comment right next to it.
