parentperf stat: Fix event grouping on forked task (diff)
perf tools: Do not disable members of group event
When event group is enabled for forked task (i.e. no target task/cpu was specified) all events were disabled and marked ->enable_on_exec. However they wouldn't be counted at all since only group leader will be enabled on exec actually. In contrast to perf stat, perf record doesn't have a real problem as it enables all the event before proceeding. But it needs to be fixed anyway IMHO.
