[ANNOUNCE] xfs-linux: iomap-for-next updated to ed1128c2d0c8

[Darrick J. Wong]

Hi folks,

The iomap-for-next branch of the xfs-linux repository at:

	git://git.kernel.org/pub/scm/fs/xfs/xfs-linux.git

has just been updated.

Patches often get missed, so please check if your outstanding patches
were in this update. If they have not been in this update, please
resubmit them to linux-xfs@vger.kernel.org so they can be picked up in
the next update.  I've been testing the xfs dio changes for a couple of
weeks now, but forgot to push them out until Christoph prompted me
yesterday.

Note that Naohiro Aota's btrfs patchset to add zoned block support will
perform some slight refactoring of fs/iomap/directio.c to add support
for REQ_OP_ZONE_APPEND.  I don't know if they're planning to push that
for 5.12, but AFAICT it should have minimal impact to everyone else.

The new head of the iomap-for-next branch is commit:

ed1128c2d0c8 xfs: reduce exclusive locking on unaligned dio

Current plan is to push that patch to 5.12 among the other zoned updates
in btrfs pull request.
