I'm getting:
        # ./iouring.2
        Kernel thread io_uring-sq is not running.
        Unable to setup io_uring: Permission denied

        # ./iouring.3s
        >>> server started, pid = 2082
        >>> memfd created, fd = 3
        io_uring_queue_init: Permission denied

I have CONFIG_IO_URING=y set, what else is needed?

I'm not sure how you tried to run those tests, but try running as root
and with SELinux in permissive mode.

Ok, they ran, including iouring.4.  iouring.2 claimed twice: "Kernel
thread io_uring-sq is not running." and I didn't get any URING records
with ausearch.  I don't know if any of this is expected.
