Now that I've written iouring.4, I would skip the others; while
helpful at the time, they are pretty crap.
I have no idea what kernel you are running, but I'm going to assume
you've applied the v2 patches (if not, you obviously need to do that
<g>). Beyond that you may need to set a filter for the
io_uring_enter() syscall to force the issue; theoretically your audit
userspace patches should allow a uring op specifically to be filtered
but I haven't had a chance to try that yet so either the kernel or
userspace portion could be broken.
At this point if you are running into problems you'll probably need to
spend some time debugging them, as I think you're the only person who
has tested your audit userspace patches at this point (and the only
one who has access to your latest bits).
