Linus Torvalds 4f016a316f New code for 5.12:
- Adjust the final parameter of iomap_dio_rw.
 - Add a new flag to request that iomap directio writes return EAGAIN if
   the write is not a pure overwrite within EOF; this will be used to
   reduce lock contention with unaligned direct writes on XFS.
 - Amend XFS' directio code to eliminate exclusive locking for unaligned
   direct writes if the circumstances permit

Merge tag 'iomap-5.12-merge-2' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull iomap updates from Darrick Wong:
 "The big change in this cycle is some new code to make it possible for
  XFS to try unaligned directio overwrites without taking locks. If the
  block is fully written and within EOF (i.e. doesn't require any
  further fs intervention) then we can let the unlocked write proceed.
  If not, we fall back to synchronizing direct writes.

  Summary:

   - Adjust the final parameter of iomap_dio_rw.

   - Add a new flag to request that iomap directio writes return EAGAIN
     if the write is not a pure overwrite within EOF; this will be used
     to reduce lock contention with unaligned direct writes on XFS.

   - Amend XFS' directio code to eliminate exclusive locking for
     unaligned direct writes if the circumstances permit"
