Ok.

I'm running audit/next (on 5.14-rc1) with your v2 patches.

I did set a syscall filter for
-a exit,always -F arch=b64 -S io_uring_enter,io_uring_setup,io_uring_register -F key=iouringsyscall
and that yielded some records with a couple of orphans that surprised me
a bit. I've attached that log. I was a bit surprised there were no
records for ./iouring.3*.

I'm now testing the new "-a uring,always -U ..." to get that userspace
code working as expected...

Yes, I'll do some basic debugging and then publish to avoid wasting
people's time on silly bugs, but to get help on the more serious ones.
