Must be weird trying to explain why Windows had to introduce a new API that they've apparently already had for 30 years.

The async I/O model is one that NT had for all that time.

The idea of using a ring data structure to do faster syscalls is what's new.

io_uring represents both a pivot to an NT style I/O model (true async instead of readiness as in epoll) using a new syscall interface.
