Pull XFS updates from Darrick Wong:
"For this release, we changed quite a few things.
Highlights:
- Fixed some long tail latency problems in the block allocator
- Removed some long deprecated (and for the past several years no-op)
mount options and ioctls
- Strengthened the extended attribute and directory verifiers
- Audited and fixed all the places where we could return EFSCORRUPTED
without logging anything
- Refactored the old SGI space allocation ioctls to make the
equivalent fallocate calls
- Fixed a race between fallocate and directio
- Fixed an integer overflow when files have more than a few
billion(!) extents
- Fixed a longstanding bug where quota accounting could be incorrect
when performing unwritten extent conversion on a freshly mounted fs
- Fixed various complaints in scrub about soft lockups and
unresponsiveness to signals
- De-vtable'd the directory handling code, which should make it
faster
- Converted to the new mount api, for better or for worse
- Cleaned up some memory leaks
and quite a lot of other smaller fixes and cleanups.
A more detailed summary:
- Fill out the build string
- Prevent inode fork extent count overflows
- Refactor the allocator to reduce long tail latency
- Rework incore log locking a little to reduce spinning
- Break up the xfs_iomap_begin functions into smaller more cohesive
parts
- Fix allocation alignment being dropped too early when the
allocation request is for more blocks than an AG is large
- Other small cleanups
- Clean up file buftarg retrieval helpers
- Hoist the resvsp and unresvsp ioctls to the vfs
- Remove the undocumented biosize mount option, since it has never
been mentioned as existing or supported on linux
- Clean up some of the mount option printing and parsing
- Enhance attr leaf verifier to check block structure
- Check dirent and attr names for invalid characters before passing
them to the vfs
- Refactor open-coded bmbt walking
- Fix a few places where we return EIO instead of EFSCORRUPTED after
failing metadata sanity checks
- Fix a synchronization problem between fallocate and aio dio
corrupting the file length
- Clean up various loose ends in the iomap and bmap code
- Convert to the new mount api
- Make sure we always log something when returning EFSCORRUPTED
- Fix some problems where long running scrub loops could trigger soft
lockup warnings and/or fail to exit due to fatal signals pending
- Fix various Coverity complaints
- Remove most of the function pointers from the directory code to
reduce indirection penalties
- Ensure that dquots are attached to the inode when performing
unwritten extent conversion after io
- Deuglify incore projid and crtime types
- Fix another AGI/AGF locking order deadlock when renaming
- Clean up some quota typedefs
- Remove the FSSETDM ioctls which haven't done anything in 20 years
- Fix some memory leaks when mounting the log fails
- Fix an underflow when updating an xattr leaf freemap
- Remove some trivial wrappers
- Report metadata corruption as an error, not a (potentially) fatal
assertion
- Clean up the dir/attr buffer mapping code
- Allow fatal signals to kill scrub during parent pointer checks"
