Subjectnfsd changes for 2.6.37
From
Please pull the following nfsd updates from the for-2.6.37 branch at:

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

Neil Brown modifed the way we wait for upcalls to solve a performance
problem and a long-standing NFSv4 correctness problem.

Pavel Emelyanov started the job of making the NFS client and server
container-aware. (Note that for the sake of keeping his work in one
tree, Trond and I agreed to merge it through my tree, though it includes
client as well as server changes.) Thanks to Chuck Lever for help with
review.

Thanks also to Tom Tucker for some rdma fixes (and review help).

I'm continuing work to bring the NFSv4.1 server close enough to the spec
that we could turn it on by default without risking future
interoperability problems. We're not quite there yet.

A moment's silence for the spkm3 code, please. It's been lying unused
for years now, so we decided to finally put it out of its misery.

We're also deprecating (not removing quite yet) the old nfsd control
interfaces.

I have a few last-minute changes still under testing that I may try to
sneak in later in the week, but given the short merge window I thought
it would make more sense to send the bulk of the changes now.

--b.
