nfsd patches for 2.6.36

nfsd patches for 2.6.36

[J. Bruce Fields]

The following nfsd changes are available from the for-2.6.36 branch of the git
repository at:

	git://linux-nfs.org/~bfields/linux.git for-2.6.36

Mainly bugfixes: for delegation/callback races, for some long-standing
vfs abuse that could cause problems with NFSv4 open upgrades, and for
some error-handling on nfsd startup (thanks to Jeff Layton).

Chuck Lever also found a nice fix for a performance problem due to our
not providing atomic directory change information, when we easily could,
leading to poor performance when e.g. untarring a large tar file.

Thanks to everyone for your contributions!
