H A D | fdmon-poll.c | diff aa38e19f05c3a5ae64dff84f44e1aa31281a5b14 Thu Mar 05 11:08:05 CST 2020 Stefan Hajnoczi <stefanha@redhat.com> aio-posix: support userspace polling of fd monitoring
Unlike ppoll(2) and epoll(7), Linux io_uring completions can be polled from userspace. Previously userspace polling was only allowed when all AioHandler's had an ->io_poll() callback. This prevented starvation of fds by userspace pollable handlers.
Add the FDMonOps->need_wait() callback that enables userspace polling even when some AioHandlers lack ->io_poll().
For example, it's now possible to do userspace polling when a TCP/IP socket is monitored thanks to Linux io_uring.
