perf: bug fix and cleanups for perf lock
PATCH 1/1 perf: bug fix and cleanups for perf lock
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.
