Merge tag 'vfs-5.18-merge-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull vfs fix from Darrick Wong:
 "The erofs developers felt that FIEMAP should handle ranged requests
  starting at s_maxbytes by returning EFBIG instead of passing the
  filesystem implementation a nonsense 0-byte request.

  Not sure why they keep tagging this 'iomap', but the VFS shouldn't be
  asking for information about ranges of a file that the filesystem
  already declared that it does not support.

   - Fix a potential infinite loop in FIEMAP by fixing an off by one
     error when comparing the requested range against s_maxbytes"
