What about use io_uring directly for polling? * Since we don't need an eventfd to bridge io_uring-aio and epoll, then we can get better performance and Linux 5.1 support. *...

Polling timerfd seems like a hack. Since if the kernel support io_uring it must support IOCB_CMD_POLL, using IOCB_CMD_POLL can be another option ( we still need to poll io_uring events...

I'm suggesting not putting liburing code into libuv's codebase. Besides their different coding style, liburing is being actively developed, it's hard to track its changes ( for example high priority...

Operations failing with EINVAL means that fd type doesn't support [read_iter](https://github.com/torvalds/linux/blob/master/fs/io_uring.c#L1101) or [write_iter](https://github.com/torvalds/linux/blob/master/fs/io_uring.c#L1148), eg tty (0, 1, 2 in your example) and timerfd ([mentioned in my comment above](https://github.com/libuv/libuv/pull/2322#issuecomment-500150292)), but seekable...
