I'd like to see some more justification as well. Namely, if I compare "setting TIF_AUDIT_SYSCALL for every process on a need-to-be-so basis" to "we always go through the slow path and pessimistically assume that audit is enabled and has reasonable ruleset loaded", I have my own (different) opinion of what is too ugly.
