I've forgot to add 'perf lock' line to command-list.txt, so users of perf could not find perf lock when they type 'perf'. Fixing command-list.txt requires document (tools/perf/Documentation/perf-lock.txt). But perf lock is too much "under construction" to write a stable document, so this is something like pseudo document for now. And I wrote description of perf lock at help section of CONFIG_LOCK_STAT, this will navigate users of lock trace events.
