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.</p> <p>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.</p> LU-3662

Allow reading from ldlm.dump_namespaces or new ldlm.namespaces.*.dump_locks file
