Merge tag 'xfs-6.1-fixes-4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs fixes from Darrick Wong:
 "Dave and I had thought that this would be a very quiet cycle, but we
  thought wrong.

  At first there were the usual trickle of minor bugfixes, but then
  Zorro pulled -rc1 and noticed complaints about the stronger memcpy
  checks w.r.t. flex arrays.

  Analyzing how to fix that revealed a bunch of validation gaps in
  validating ondisk log items during recovery, and then a customer hit
  an infinite loop in the refcounting code on a corrupt filesystem.

  So. This largeish batch of fixes addresses all those problems, I hope.

  Summary:

   - Fix a UAF bug during log recovery

   - Fix memory leaks when mount fails

   - Detect corrupt bestfree information in a directory block

   - Fix incorrect return value type for the dax page fault handlers

   - Fix fortify complaints about memcpy of xfs log item objects

   - Strengthen inadequate validation of recovered log items

   - Fix incorrectly declared flex array in EFI log item structs

   - Log corrupt log items for debugging purposes

   - Fix infinite loop problems in the refcount code if the refcount
     btree node block keys are corrupt

   - Fix infinite loop problems in the refcount code if the refcount
     btree records suffer MSB bitflips

   - Add more sanity checking to continued defer ops to prevent
     overflows from one AG to the next or off EOFS"
