Subject: perf lock: Add --synth=no option for record
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=67b61f59a620450738caf69552efa85faa9637f9;p=uclinux-h8%2Flinux.git

perf lock: Add --synth=no option for record

The perf lock command has nothing to symbolize and lock names come
from the tracepoint.  Moreover, kernel symbols are available even the
--synth=no option is given.

This will reduce the startup time by avoiding unnecessary synthesis.
