This wraps epoll and io_uring the other way: previously, we had the io_uring file descriptor registered in epoll and when it became ready, we could query its completion ring. The problem is that the poll wakeups cause considerable overhead in the Linux kernel, see https://lore.kernel.org/io-uring/20250128133927.3989681-9-max.kellermann@ionos.com/ By wrapping epoll inside io_uring using io_uring_prep_poll_multishot(), the "outer" loop is io_uring and inside it, we have epoll. This adds another system call for epoll, but that will go away as soon as most operations are going through io_uring. Previously, io_uring had this extra system call.
