From 84c6f88fc8265d7a712d7d6ed8fc1a878dfc84d1 Mon Sep 17 00:00:00 2001 From: Hitoshi Mitake Date: Thu, 4 Feb 2010 16:08:15 +0900 Subject: perf lock: Fix and add misc documentally things 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.
