Cover letter [PATCH 0/6 V2] xfs: upfront block zeroing for DAX
Hi folks,
This is an updated patch set that was first posted here:
http://oss.sgi.com/archives/xfs/2015-10/msg00006.html
I've dropped the DAX locking revert patch from it; that's on it's way to Linus via other channels and is essentially independent to this set of XFS changes.
The only real change in the XFS code between the two versions is the addition of XFS_TRANS_RESERVE in the DAX path in xfs_iomap_write_direct() to allow it to dip into the reserve block pool for unwritten extent conversion rather than reporting ENOSPC.
Patches are against 4.3-rc5 + XFS for-next branch.
-Dave.
