[PATCH] knfsd: lockd: make nlm_traverse_* more flexible
This patch makes nlm_traverse{locks,blocks,shares} and friends use a function pointer rather than a "action" enum. This function pointer is given two nlm_hosts (one given by the caller, the other taken from the lock/block/share currently visited), and is free to do with them as it wants. If it returns a non-zero value, the lockd/block/share is released.
