lkdtm: add debugfs access and loosen KPROBE ties

2010-03-06T19:26:32Z

Add adds a debugfs interface and additional failure modes to LKDTM to provide similar functionality to the provoke-crash driver submitted here: http://lwn.net/Articles/371208/ Crashes can now be induced either through module parameters (as before) or through the debugfs interface as in provoke-crash. The patch also provides a new "direct" interface, where KPROBES are not used, i.e., the crash is invoked directly upon write to the debugfs file. When built without KPROBES configured, only this mode is available. Signed-off-by: Simon Kagstrom Cc: M. Mohan Kumar Cc: Americo Wang Cc: David Woodhouse Cc: Ingo Molnar Cc: "Eric W.

perf lock: Fix and add misc documentally things

2010-02-27T16:05:22Z

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.

rcu: Add RCU_CPU_STALL_VERBOSE to dump detailed per-task information

2010-02-25T09:35:02Z

When RCU detects a grace-period stall, it currently just prints out the PID of any tasks doing the stalling. This patch adds RCU_CPU_STALL_VERBOSE, which enables the more-verbose reporting from sched_show_task(). Suggested-by: Thomas Gleixner Signed-off-by: Paul E.
