nfs server patches for 2.6.25

[J. Bruce Fields]

Below is a summary of the nfs server patches which I expect to submit
(any day now) for 2.6.25; please let me know if you notice anything
wrong or missing.  I'll follow up to linux-nfs@xxxxxxxxxxxxxxx with the
full list of patches.

The biggest changes come from Tom Tucker's rdma and server transport
switch patches, which Chuck Lever, Greg Banks, Neil Brown, and others
helped review (thanks!).  The rest is mostly bug fixes and cleanup.

As a reminder, you can see the patches I've got queued up any time from
the nfs-server-stable branch at:
