 - Ensure that memory buffers for IO are properly sector-aligned to avoid
   problems that the block layer doesn't check.
 - Make the bmap scrubber more efficient in its record checking.
 - Don't crash xfs_db when superblock inode geometry is corrupt.
 - Fix btree key helper functions.
 - Remove unneeded error returns for things that can't fail.
 - Fix buffer logging bugs in repair.
 - Clean up iterator return values.
 - Speed up directory entry creation.
 - Enable allocation of xattr value memory buffer during lookup.
 - Fix readahead racing with truncate/punch hole.
 - Other minor cleanups.
 - Fix one AGI/AGF deadlock with RENAME_WHITEOUT.
 - More BUG -> WARN whackamole.
 - Fix various problems with the log failing to advance under certain
   circumstances, which results in stalls during mount.

Merge tag 'xfs-5.4-merge-7' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs updates from Darrick Wong:
 "For this cycle we have the usual pile of cleanups and bug fixes, some
  performance improvements for online metadata scrubbing, massive
  speedups in the directory entry creation code, some performance
  improvement in the file ACL lookup code, a fix for a logging stall
  during mount, and fixes for concurrency problems.

  It has survived a couple of weeks of xfstests runs and merges cleanly.

  Summary:

   - Remove KM_SLEEP/KM_NOSLEEP.

   - Ensure that memory buffers for IO are properly sector-aligned to
     avoid problems that the block layer doesn't check.

   - Make the bmap scrubber more efficient in its record checking.

   - Don't crash xfs_db when superblock inode geometry is corrupt.

   - Fix btree key helper functions.

   - Remove unneeded error returns for things that can't fail.

   - Fix buffer logging bugs in repair.

   - Clean up iterator return values.

   - Speed up directory entry creation.

   - Enable allocation of xattr value memory buffer during lookup.

   - Fix readahead racing with truncate/punch hole.

   - Other minor cleanups.

   - Fix one AGI/AGF deadlock with RENAME_WHITEOUT.

   - More BUG -> WARN whackamole.

   - Fix various problems with the log failing to advance under certain
     circumstances, which results in stalls during mount"
