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.
