Merge tag 'iomap-5.4-merge-6' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull iomap updates from Darrick Wong:
 "After last week's failed pull request attempt, I scuttled everything
  in the branch except for the directio endio api changes, which were
  trivial. Everything else will simply have to wait for the next cycle.

  Summary:

   - Report both io errors and short io results to the directio endio
     handler.

   - Allow directio callers to pass an ops structure to iomap_dio_rw"

* tag 'iomap-5.4-merge-6' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux:
  iomap: move the iomap_dio_rw ->end_io callback into a structure
  iomap: split size and error for iomap_dio_rw ->end_io
