Subject: [PATCH] perf lock: Change to synthesize task events
Date: Thu, 26 May 2022 14:31:36 -0700 [thread overview]
Message-ID: <20220526213136.193404-1-namhyung@kernel.org> (raw)
With -t/--threads option, it needs to display task names so synthesize
task related events at the beginning.
Fixes: 7c3bcbdf449f ("perf lock: Add -t/--thread option for report")
Signed-off-by: Namhyung Kim <namhyung@kernel.org>
