Yes, I wish I could do that, but that works only if everything is io_uring - all or nothing. Most of the code is built around an epoll-based loop and will not be ported to io_uring so quickly. Maybe what's missing is epoll_wait as io_uring opcode. Then I could wrap it the other way. Or am I supposed to use io_uring poll_add_multishot for that? Max
