[ FWIW PTRACE_MODE_NOAUDIT being in PTRACE_MODE_IBPB goes back to original Tim's pre-CRD patchset ]
Well, we can't really call out into audit from scheduler code, and the previous versions of the patchsets didn't have PTRACE_MODE_SCHED, so it had to be included in PTRACE_MODE_IBPB in order to make sure we're not calling into audit from context switch code.
Or did I misunderstand the question?
