Hi folks,

I've just updated both the master and for-next branches of
the linux-xfs tree here:

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

Th emaster branch has been updated to v4.19 so that I can base the
dedupe/clone rework off it without needing to care about conflicts
in 4.19-rc7/-rc8. The for-next branch contains the that rework, and
the details are below. I'm going to let this sit in linux-next for a
couple of days, then ask Linus to pull it if nothing goes awry with
it.

Cheers,

Dave.
