This includes Christoph's branch (all but the final xfs commits):

	git://linux-nfs.org/~bfields/linux.git for-3.20

That's what I intend to submit.  Hope that's OK.  Then it's up to Dave
whether he wants to pull that in and include the xfs patches.

Worst case we end up with not-yet-usable pnfs code in 3.20, which
wouldn't be ideal but shouldn't cause any serious problem either.
