2018-01-17xfs: cross-reference the realtime bitmapDarrick J. Wong1-0/+21
While we're scrubbing various btrees, cross-reference the records with the other metadata. Signed-off-by: Darrick J. Wong <[email protected]> Reviewed-by: Dave Chinner <[email protected]>
2017-10-31xfs: remove redundant assignment to variable bitColin Ian King1-1/+0
Variable bit is being assigned a value that is never read, hence the assignment is redundant and can be removed. Cleans up clang warning: fs/xfs/libxfs/xfs_rtbitmap.c:675:3: warning: Value stored to 'bit' is never read Signed-off-by: Colin Ian King <[email protected]> Reviewed-by: Darrick J.

2017-10-26xfs: create block pointer check functionsDarrick J. Wong1-0/+12
Create some helper functions to check that a block pointer points within the filesystem (or AG) and doesn't point at static metadata. We will use this for scrub. Signed-off-by: Darrick J. Wong <[email protected]> Reviewed-by: Dave Chinner <[email protected]>
2017-06-19xfs: export various function for the online scrubberDarrick J. Wong1-1/+1
Export various internal functions so that the online scrubber can use them to check the state of metadata. Signed-off-by: Darrick J. Wong <[email protected]> Reviewed-by: Brian Foster <[email protected]>
2017-06-19xfs: remove double-underscore integer typesDarrick J. Wong1-1/+1
This is a purely mechanical patch that removes the private __{u,}int{8,16,32,64}_t typedefs in favor of using the system {u,}int{8,16,32,64}_t typedefs. This is the sed script used to perform the transformation and fix the resulting whitespace and indentation errors: s/typedef\t__uint8_t/typedef __uint8_t\t/g s/typedef\t__uint/typedef __uint/g s/typedef\t__int\([0-9]*\)_t/typedef int\1_t\t/g s/__uint8_t\t/__uint8_t\t\t/g s/__uint/uint/g s/__int\([0-9]*\)_t\t/__int\1_t\t\t/g s/__int/int/g /^typedef.*int[0-9]*_t;$/d Signed-off-by: Darrick J.

2017-04-03xfs: add a couple of queries to iterate free extents in the rtbitmapDarrick J. Wong1-0/+70
Add _query_range and _query_all functions to the realtime bitmap allocator. These two functions are similar in usage to the btree functions with the same name and will be used for getfsmap and scrub. Signed-off-by: Darrick J. Wong <[email protected]> Reviewed-by: Brian Foster <[email protected]>

2016-06-01xfs: make several functions staticEric Sandeen1-1/+1
Al Viro noticed that xfs_lock_inodes should be static, and that led to ... a few more. These are just the easy ones, others require moving functions higher in source files, so that's not done here to keep this review simple.

2016-02-09xfs: remove timestamps from incore inodeDave Chinner1-1/+1
The struct xfs_inode has two copies of the current timestamps in it, one in the vfs inode and one in the struct xfs_icdinode. Now that we no longer log the struct xfs_icdinode directly, we don't need to keep the timestamps in this structure. instead we can copy them straight out of the VFS inode when formatting the inode log item or the on-disk inode. This reduces the struct xfs_inode in size by 24 bytes.

2016-02-09xfs: RT bitmap and summary buffers need verifiersDave Chinner1-1/+26
Buffers without verifiers issue runtime warnings on XFS. We don't have anything we can actually verify in the RT buffers (no CRCs, not magic numbers, etc), but we still need verifiers to avoid the warnings. Add a set of dummy verifier operations for the realtime buffers and apply them in the appropriate places.

2016-02-09xfs: RT bitmap and summary buffers are not typedDave Chinner1-0/+3
When logging buffers, we attach a type to them that follows the buffer all the way into the log and is used to identify the buffer contents in log recovery. Both the realtime summary buffers and the bitmap buffers do not have types defined or set, so when we try to log them we see assert failure: XFS: Assertion failed: (bip->bli_flags & XFS_BLI_STALE) || (xfs_blft_from_flags(&bip->__bli_format) > XFS_BLFT_UNKNOWN_BUF && xfs_blft_from_flags(&bip->__bli_format) < XFS_BLFT_MAX_BUF), file: fs/xfs/xfs_buf_item.c, line: 294 Fix this by adding buffer log format types for these buffers, and add identification support into log recovery for them. Only build the log recovery support if CONFIG_XFS_RT=y - we can't get into log recovery for real time filesystems if support is not built into the kernel, and this avoids potential build problems.

More consolidatation for the on-disk format defintions. Note that the XFS_IS_REALTIME_INODE moves to xfs_linux.h instead as it is not related to the on disk format, but depends on a CONFIG_ option.

xfs_rtmodify_summary and xfs_rtget_summary are almost identical; fold them into xfs_rtmodify_summary_int(), with wrappers for each of the original calls. The _int function modifies if a delta is passed, and returns a summary pointer if *sum is passed.
