No it doesn't.  This is insane and absurd.

You know my views on this crappy audit stuff, I made myself pretty clear
after we discovered the back door merging of this code which had zero
review from ARM people, and my view on that has just been reinforced by
your comments which clearly indicate that there's no way this has ever
been properly tested.

It should have never gone into the mainline kernel.
