Normally I would've just deferred it to next week, but since the original fix got picked up by stable, I think it's better to just send this one off separately. The issue is around the poll race fix, and how it mistakenly also got applied to multishot polling. Those don't need the race fix, and we should not be doing any reissues for that case. Exhaustive test cases were written and committed to the liburing regression suite for the reported issue, and additions for similar issues. Please pulL!
