Also, it does indeed race with
__perf_event_exit_task()/sync_child_event(), but that one I'd fix by
simply wrapping the sync_child_event()/free_event() in
mutex_lock(&parent_event->child_mutex);
if (!is_orphan_event(parent_event)) {
sync_child_event(child_event);
free_event(child_event);
}
mutex_unlock(&parent_event->child_event);
At some later point in time the code there could use a bit of
reshuffling, I guess.
