Subject: [GIT PULL] xfs: fixes for 4.9-rc3

Hi Linus,

Can you please pull the fixes from the tag below? This update
contains fixes for most of the outstanding regressions introduced
with the 4.9-rc1 XFS merge. There is also a fix for an iomap bug,
too.

This is a quite a bit larger than I'd prefer for a -rc3, but most of
the change comes from cleaning up the new reflink copy on write
code; it's much simpler and easier to understand now. These changes
fixed several bugs in the new code, and it wasn't clear that
there was an easier/simpler way to fix them.  The rest of the fixes
are the usual size you'd expect at this stage.

I've left the commits to soak in linux-next for a some extra time
because of the size before asking you to pull, no new problems with
them have been reported so I think it's all OK. Let me if you
disagree and want me to do this differently.

-Dave.
