Subject: [PATCH 08/12] perf ui/gtk: Add support for event group view
From: Namhyung Kim <namhyung.kim@....com>
Show group members' overhead also when showing the leader's if event
group is enabled. At this time, only implemented overhead part in
order to ease review and other parts can be added later once this
patch settled down.
