why?

i-- < 0 is always false, since i is unsigned. Even if it was signed, it would still be false anyway, since i is always positive. I think this was meant to be a greater than rather than a less than?

How is this passing tests?

Can a test be added to trigger this issue? It seems like maybe this entire case is currently missed (or would indeed surely be failing).

I added a test for this code path, but what that test verified is that the correct events are not removed from the list, not whether the intended events are removed. So not removing any events makes the test pass :)

This loop is intended to remove unneeded events from a waitlist. It's a performance optimization and may be needed to workaround (what I think is) a driver issue.
