#     Merge tag 'xfs-5.20-merge-6' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
#     
#     Pull xfs updates from Darrick Wong:
#      "The biggest changes for this release are the log scalability
#       improvements, lockless lookups for the buffer cache, and making the
#       attr fork a permanent part of the incore inode in preparation for
#       directory parent pointers.
#     
#       There's also a bunch of bug fixes that have accumulated since -rc5. I
#       might send you a second pull request with some more bug fixes that I'm
#       still working on.
#     
#       Once the merge window ends, I will hand maintainership back to Dave
#       Chinner until the 6.1-rc1 release so that I can conduct the design
#       review for the online fsck feature, and try to get it merged.
#     
#       Summary:
#     
#        - Improve scalability of the XFS log by removing spinlocks and global
#          synchronization points.
#     
#        - Add security labels to whiteout inodes to match the other
#          filesystems.
#     
#        - Clean up per-ag pointer passing to simplify call sites.
#     
#        - Reduce verifier overhead by precalculating more AG geometry.
#     
#        - Implement fast-path lockless lookups in the buffer cache to reduce
#          spinlock hammering.
#     
#        - Make attr forks a permanent part of the inode structure to fix a
#          UAF bug and because most files these days tend to have security
#          labels and soon will have parent pointers too.
#     
#        - Clean up XFS_IFORK_Q usage and give it a better name.
#     
#        - Fix more UAF bugs in the xattr code.
#     
#        - SOB my tags.
#     
#        - Fix some typos in the timestamp range documentation.
#     
#        - Fix a few more memory leaks.
#     
#        - Code cleanups and typo fixes.
#     
#        - Fix an unlocked inode fork pointer access in getbmap"
