io_uring and timeout

[Nazar2]

Hello guys.

I'm building a real time relay service using io_uring and want to know which of *timeout function should I use. There are three of them: io_uring_prep_timeout vs io_uring_prep_link_timeout vs io_uring_submit_and_wait_timeout.

What I want is to react when read/write operations timed out and execute some code.
