2.6.37 nfsd changes

["J. Bruce Fields" <bfields@fieldses.org>]

The changes I've already committed for the 2.6.37 submission are
available from

	git://linux-nfs.org/~bfields/linux.git for-2.6.37

(summary below).  I'm also hoping to sneak in some more sessions
patches, but the merge window is opened, so I'll submit this to Linus
soon.

Any testing of that branch is appreciated; it passes all my usual tests,
so hopefully it's not too hairy.
