You would save on kernel image size (code is compiled out) and
possibly some performance gains, but I'm not entirely sure of that
last point, I would need to go check the code a bit more. However, I
think the better question is, how useful are file watches without the
associated syscall record? I'm going to say "not very". Also, it is
probably moot, because as we mentioned earlier, I just don't believe
there is anyone using audit who disables syscall auditing - it just
doesn't make much sense.

I'd be very surprised to hear if anyone is running audit *without* syscall auditing,
but I thought I would toss the question out there on the off chance I'm missing some
critical use case.

I'm thinking of simply removing the CONFIG_AUDITSYSCALL knob and moving all that code
under CONFIG_AUDIT, does anyone have any objections?
