Merge tag 'xfs-5.10-fixes-7' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs fixes from Darrick Wong:
 "The critical fixes are for a crash that someone reported in the xattr
  code on 32-bit arm last week; and a revert of the rmap key comparison
  change from last week as it was totally wrong. I need a vacation. :(

  Summary:

   - Fix various deficiencies in online fsck's metadata checking code

   - Fix an integer casting bug in the xattr code on 32-bit systems

   - Fix a hang in an inode walk when the inode index is corrupt

   - Fix error codes being dropped when initializing per-AG structures

   - Fix nowait directio writes that partially succeed but return EAGAIN

   - Revert last week's rmap comparison patch because it was wrong"
