I assume your bug happened in io_uring_create(), and if so
fwiw confirm that your patch looks right ...

... if the mentioned commit fixes the issue, then we should
backport it, because
1) there is more to that patch, so should be done in any case
2) stable _highly_ prefers to take commits from upstream, but not
newly crafted ones.
However, that might be useless because a large chunk of patch
that's to be ported soon.
