Created kernel tracking bugs for this issue: Affects: fedora-all [bug 1353534] (In reply to Andrej Nemec from comment #0) > Upstream patch: > > https://github.com/linux-audit/audit-kernel/issues/18 I don't actually see a patch there. That's an issue, which is the equivalent of this bug. Paul, I'm guessing a patch is in the works?

I checked git and this particular patch is not there yet imo. (In reply to Josh Boyer from comment #2) > Paul, I'm guessing a patch is in the works? It is on my radar but I haven't gotten to it yet.
