[PATCH] perf: bug fix and cleanups for perf lock

[Stephane Eranian]

This patch fixes the event names used by perf lock. The :r suffix
is not supported anymore, it seems.

The patch also cleans up the help and man page to reflect
actual options. The perf lock trace option does not exist
anymore, AFAICT. When you use it, you get an error but you
have no idea why.
