    Yes, when I saw this original posting I did discuss it with Pavel as
    well, and we agree that the same issue exists there. Which isn't too
    surprising, as that's where the io_uring poll code from originally.

    Eric, do you have a test case for this? aio is fine, we can convert it
    to io_uring as well. Would be nice for both verifying the fix, but also
    to carry in the io_uring regression tests for the future.
