Merge tag 'xfs-6.4-merge-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs updates from Dave Chinner:
 "This consists mainly of online scrub functionality and the design
  documentation for the upcoming online repair functionality built on
  top of the scrub code:

   - Added detailed design documentation for the upcoming online repair
     feature

   - major update to online scrub to complete the reverse mapping
     cross-referencing infrastructure enabling us to fully validate
     allocated metadata against owner records. This is the last piece of
     scrub infrastructure needed before we can start merging online
     repair functionality.

   - Fixes for the ascii-ci hashing issues

   - deprecation of the ascii-ci functionality

   - on-disk format verification bug fixes

   - various random bug fixes for syzbot and other bug reports"
