Minor Description
Imperative lock dumping via writes to /proc/fs/lustre/ldlm/dump_namespaces only works once every 10 seconds because of the rate limitation imposed by ns_next_dump. Since ldlm_expired_completion_wait() has it's own 5 minute rate limit, it seems best just to do away with ns_next_dump altogether.
It would also be nice if we had a per namespace dump trigger and if we could just cat that file to get the dump rather than having to get it from the logs.
