Completely untested and I know nothing about aio, thus needs an ack
from maintainers or should be ignored.

But exit_aio() looks "obviously unnecessarily overcomplicated", I was
really puzzled when I looked at this code by accident.

Kent, could you also explain kioctx->dead is atomic_t? This looks
pointless? afaics atomic_ buys nothing in this case.

Oleg.
