Auditing io_uring

Large scale customers I worked for in the past I saw flamegraphs where they had audit on with a number of rules. Man.. audit took ~80% of the cycles that were needed for the syscall and ~20% just for the actual logic. If you can just turn it off by default and opt-in globally the speedup is really immense. No wonder people complain kernel is too slow. Because of regulations or whatever the argument is here is <1% of kernel users.
