By removing the spinlock around ring insertion, you've made it possible
for two events being inserted on different CPUs to end up creating
inconsistent state, as there is nothing which guarantees that resulting
event in the ring will be wholely one event or another.
Also, I don't like rounding up of the number of events to the nearest power
of two, as it can round things up significantly more than just going to the
end of the last actual page of memory allocated.
