nfsv4 server patches and status

[J. Bruce Fields]

These are some miscellaneous patches I have outstanding for the nfsv4
server.

The first is a resend of the patch that brings lockd and nfsd grace
periods into agreement, this time with the circular module dependency
fixed.  This is a minimal fix which still leaves a small race at the end
of the grace period.  We've got a larger reboot recovery fix on the way
(probably for after 2.6.23) that should make this all a lot more
straightforward, so I don't want to do anything more complicated till
then.

The last couple patches are minor steps on another long-term project:
figuring out how to make good use of NFSv4 delegations.  We've got a
new student experimenting with that this summer (Meelap Shah), so you
may be hearing some more from him.

All this is also available from

	git://linux-nfs.org/~bfields/linux.git nfs-server-stable

The only other server-side patches I have outstanding right now are
those secinfo patches.
