perf_events: Move code around to prepare for cgroup
In particular this patch move perf_event_exit_task() before cgroup_exit() to allow for cgroup support. The cgroup_exit() function detaches the cgroups attached to a task. Other movements include hoisting some definitions and inlines at the top of perf_event.c Signed-off-by: Stephane Eranian <eranian@google.com> Signed-off-by: Peter Zijlstra <a.p.zijlstra@chello.nl> LKML-Reference: <4d22058b.cdace30a.4657.ffff95b1@mx.google.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
