Subject: [PATCH v3 0/3] xfs and DAX atomic writes changes

This series contains an atomic writes fix for DAX support on xfs and
an improvement to WARN against using IOCB_ATOMIC on the DAX write path.

Also included is an xfs atomic writes mount option fix.

Based on xfs -next at ("b0494366bd5b Merge branch 'xfs-6.17-merge' into
for-next")

John Garry (3):
  fs/dax: Reject IOCB_ATOMIC in dax_iomap_rw()
  xfs: disallow atomic writes on DAX
  xfs: reject max_atomic_write mount option for no reflink
