PS2: IMHO this shouldn't happen if we use a big-enough ring size. If at all, an envvar to change the global io_uring ring-size could be used, but I doubt this is needed.

Do you mind explaining better how do you end up in this situation where you fill the ring?

If the ring is full can't we simply delay adding a new sqe until it becomes non-full?

Re-creating the io_uring seems like a bad decision imho.
