There is no race concern: hrtimer_start() is internally serialized and
safe to call on an active timer. In the event of a race between
hrtimer_active() and hrtimer_start(), the worst case is calling
hrtimer_start() on an already-active timer, which is identical to the
pre-patch behaviour.

I mean.. I wouldn't say that this is not racy. But I think you're not
making it much worse than it already was :S

Could you experiment with deleting all this local driver logic and just
relying on NAPI's built-in defer IRQ mechanism?
