These patches make a few tweaks that improve the performance of ALLOCATE and DEALLOCATE requests. The first patch attempts to update cache information after a (DE)ALLOCATE call, rather than clearing the cache and forcing the client to re-read the file later. The second patch changes when we lock the i_mutex to give NFS v4.0 and v4.1 a chance to exit without taking a lock. Comments are appreciated!
