#     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"
