There should no longer be any - read - write - connect - sendmsg - recvmsg - accept calls in the codebase. Previously we were using a mix of io_uring and these calls which had some negative effects: Since we were using the old system calls, we had to set the file descriptors to non-blocking. But our io_uring code did not handle EAGAIN. This lead to programs sometimes being killed when the wayland IO was actually blocking. Now all file descriptors are set to blocking, but io_uring makes it non-blocking from our perspective. The one exception are evdev files because they are read via libinput and libinput uses the old system calls.
