Would you have a source line for me that goes with that.. I can't seem
to poke any holes just by looking.
perf_swevent_init() only sets event->destroy() (to
sw_perf_event_destroy) _after_ it increments the static key thing and
enqueues (and allocates) the hash list stuff.
Obviously something is funny, but I'm not seeing it.
