There's a pre-131-2 patch there on ftp.kernel.org in the testing
directory. This should have the NFS locking issues worked out (please
test), and also has a rather subtle but potentially very nasty deadlock
due to incorrect semaphore ordering with rmdir() hopefully fixed for good.
Alan, the regparm patches are also there.

nfs: write back everything whenever some lock is changed (not just for
     unlock), and always invalidates the caches.
