Thanks for the patch...but we probably should have talked a bit more before 
undertaking this effort. We normally do not audit from user space what happens 
in the kernel. Doing this can be racy and it keeps auditd from doing the one 
job it has - which is to grab events and record them to disk and send them 
out the realtime interface.

Hmm. The email I remember was here:
https://www.redhat.com/archives/linux-audit/2018-October/msg00053.html

and was only 2 emails long with no answer to my question. :-)

I'd like to understand what the basic problem is that needs to be solved.
