Peter Zijlstra c6e5b73242 perf: Synchronously clean up child events ... The orphan cleanup workqueue doesn't always catch orphans, for example, if they never schedule after they are orphaned. IOW, the event leak is still very real. It also wouldn't work for kernel counters. Doing it synchonously is a little hairy due to lock inversion issues, but is made to work. Patch based on work by Alexander Shishkin.
