#     Merge tag 'xfs-5.1-merge-4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
#     
#     Pull xfs updates from Darrick Wong:
#      "Here are a number of new features and bug fixes for 5.1
#     
#       They've undergone a week's worth of fstesting and merge cleanly with
#       master as of this morning
#     
#       Most of the changes center on improving metadata validation and fixing
#       problems with online fsck, though there's also a new cache to speed up
#       unlinked inode handling and cleanup of the copy on write code in
#       preparation for future features
#     
#       Changes for Linux 5.1:
#     
#        - Fix online fsck to handle inode btrees correctly on 64k block
#          filesystems
#     
#        - Teach online fsck to check directory and attribute names for
#          invalid characters
#     
#        - Miscellanous fixes for online fsck
#     
#        - Introduce a new panic mask so that we can halt immediately on
#          metadata corruption (for debugging purposes)
#     
#        - Fix a block mapping race during writeback
#     
#        - Cache unlinked inode list backrefs in memory to speed up list
#          processing
#     
#        - Separate the bnobt/cntbt and inobt/finobt buffer verifiers so that
#          we can detect crosslinked btrees
#     
#        - Refactor magic number verification so that we can standardize it
#     
#        - Strengthen ondisk metadata structure offset build time verification
#     
#        - Fix a memory corruption problem in the listxattr code
#     
#        - Fix a shutdown problem during log recovery due to unreserved finobt
#          expansion
#     
#        - Fix a referential integrity problem where O_TMPFILE inodes were put
#          on the unlinked list with nlink > 0 which would cause asserts
#          during log recovery if the system went down immediately
#     
#        - Refactor the delayed allocation allocator to be more clever about
#          the possibility that its mapping might be stale
#     
#        - Various fixes to the copy on write mechanism
#     
#        - Make CoW preallocation suitable for use even with writes that
#          wouldn't otherwise require it
#     
#        - Refactor an internal API
#     
#        - Fix some statx implementation bugs
#     
#        - Fix miscellaneous compiler and static checker complaints"
