[NOTE: adding the audit list to the CC line]

Sorry, I read your email too quickly; you are correct, that commit
fixed a different problem.

Let me think on this a bit more.  Technically I don't see this as a
bug with the kernel, userspace is enabling audit and you are getting
audit messages as a result; from my opinion this is the expected
behavior.  However, we've talked in the past about providing better
control over seccomp's auditing/logging and that work would allow you
to quiet all seccomp messages if you desired.

If you are interested, I started tracking this issue at the link below:
