Hi Linus,
Just a single fix for a regression that happened in this release due to
a poll change. 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!
