nfsd changes for 2.6.31

[J. Bruce Fields]

The following nfsd-related changes are available from the for-2.6.31
branch at:

  git://fieldses.org/git/linux-nfsd.git for-2.6.31

(Not the usual URL: CITI is moving tomorrow and linux-nfs.org won't be
up reliably for the next couple days, so I'm hosting this temporarily on
my personal server.)

This includes a few small preliminaries for further 4.1 changes
(backchannel support and a DRC overhaul), but most of that will be
queued up for 2.6.32.

The NFSv4 server will now use ext4's i_version when available, though
some more ext4 changes, and testing of performance impact, are needed to
make it usable.

The rest is miscellaneous cleanup and bugfixes.  Thanks to everyone who
contributed!
