Subject: [PATCH 17/19] perf report: Add --group option
Date: Tue, 22 Jan 2013 18:09:45 +0900 [thread overview]
Message-ID: <1358845787-1350-18-git-send-email-namhyung@kernel.org> (raw)

Add --group option to enable event grouping. When enabled, all the
group members information will be shown together with the leader.
$ perf report --group
