This is also on my todo list, but it sits behind fixing one last
libseccomp bug and getting a new release out.  I made some good
progress on the libseccomp bug right before the holiday, but I think
there is still a days worth of work left before it is ready to be
merged.  I'm also traveling for the next week so I doubt I'll have any
serious time to devote to the kernel patch(es).

I can't remember what Tyler's last thought was on the logic, but I
imagine I'll just wait until I see some patches to review/merge, or I
can go back in the thread if I happen to have time before anyone else.

Also, to set expectations, since we are currently at -rc6, this is
likely going to need to wait until 4.17 at the earliest as I generally
don't like merging new functionality in the last week or two before
the merge window.

Also (part two), we should add a test case to the audit-testsuite for
any new knobs that affect the SECCOMP records.
