nfsd for 2.6.38

[J. Bruce Fields]

Please pull nfsd development for 2.6.38 from:

  git://linux-nfs.org/~bfields/linux.git for-2.6.38

This includes a first implementation of session trunking support and
secinfo_no_name support, both mandatory features for NFSv4.1.  My list
of issues that I believe we need fixed before server-side 4.1 can be
considered minimally correct is at

  http://wiki.linux-nfs.org/wiki/index.php/Server_4.0_and_4.1_issues

I want to see that list done before we start merging optional 4.1
features such as pNFS.  At my current rate I'm not sure when we'll get
there--not soon.

Also included is a stopgap measure to fix a longstanding failure to
revoke delegations in all the cases we should.  It still leaves some
races (and doesn't deal with local or Samba conflicts), so I hope to
have a more complete solution ready for 2.6.39.

And some other miscellaneous cleanup and bugfixing.  Thanks especially
to Mi Jinlong at Fujitsu, who has been writing tests and catching bugs
in the new 4.1 code.
