I'll try to read (and hopefully even understand ;) this patch carefully,
but at first glance this should work.
Personally, as a _reader_ of this code, I like the fact that
perf_event_release_kernel() does perf_remove_from_context() instead of
_disable + del_event. IMHO, this makes the things more understandable.
Oleg.
