[GIT PULL] xfs: updates for 4.9-rc1

[Dave Chinner]

Hi Linus,

Can you please pull the XFS and iomap updates from the tag listed
below? The main things in this update are the iomap-based DAX
infrastructure, an XFS delalloc rework, and a chunk of fixes to how
log recovery schedules writeback to prevent spurious corruption
detections when recovery of certain items was not required.

The other main chunk of code is some preparation for the upcoming
reflink functionality. Most of it is generic and cleanups that stand
alone, but they were ready and reviewed so are in this pull request.

Speaking of reflink, I'm currently planning to send you another pull
request next week containing all the new reflink functionality.  I'm
working through a similar process to the last cycle, where I sent
the reverse mapping code in a separate request because of how large
it was. The reflink code merge is even bigger than reverse mapping,
so I'll be doing the same thing again....

Thanks,

-Dave.
