From fc24d7c25c9d880ae012548d522fe13caee556ed Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Tue, 22 Jan 2013 18:09:43 +0900 Subject: [PATCH] perf report: Bypass non-leader events when event group is enabled Since we have all necessary information in the leader events and other members don't, bypass members. Member events will be shown along with the leaders if event group is enabled.
