[ANNOUNCE] xfs-linux: iomap-for-next updated to b7b293bdaaf4

[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.

The branch now contains three major API changes for 5.5: Jan's explicit
synchronous iomap_dio_rw parameter; Christoph's porting of the xfs
writeback implementation to iomap; and Goldwyn/Christoph's addition of
srcmap support to iomap_begin for COW staging.  I think this is it for
5.5, modulo any bug fixes anyone wants to submit.  If anyone sees
anything bad enough to warrant a push -f, please scream quickly,
otherwise I'll consider this branch a stable working branch on 22 Oct
2019 at 00:00 UTC.  (Extra time because I'm sending this late on a
Friday afternoon.)

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

b7b293bdaaf4 iomap: use a srcmap for a read-modify-write I/O

I think this one if 5.4/-stable material.
