Merge branch 'for-3.7' of git://linux-nfs.org/~bfields/linux
Pull nfsd update from J Bruce Fields:
"Another relatively quiet cycle. There was some progress on my
remaining 4.1 todo's, but a couple of them were just of the form
"check that we do X correctly", so didn't have much affect on the
code.
Other than that, a bunch of cleanup and some bugfixes (including an
annoying NFSv4.0 state leak and a busy-loop in the server that could
cause it to peg the CPU without making progress)."
