From 717e263fc354d53d0961e952b779d14a42c8ea66 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Tue, 22 Jan 2013 18:09:44 +0900 Subject: perf report: Show group description when event group is enabled When using event group viewer, it's better to show the group description rather than the leader information alone. If a leader did not contain any member, it's a non-group event.
