    [ 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?

    Thanks,
