Stop gthis f*cking idiocy already!

As far as the kernel is concerned, a regressions is THE KERNEL NOT

The regression was in the kernel. You trying to shift the regressions
somewhere  else is bogus SHIT.

And seriously, it's the kind of garbage that makes me think your
opinion and your code cannot be relied on.

If you are not willing to admit that your commit 651e28c5537a
("apparmor: add base infastructure for socket mediation") caused a
regression, then honestly, I don't want to get commits from you.

It's that simple.

I'm *very* unhappy with the security layer as is, the last thing I
want to see is some security layer developer that then goes on to try
to re-define was regression means.

If you break existing user space setups THAT IS A REGRESSION.

It's not ok to say "but we'll fix the user space setup".

Really. NOT OK.

I think I will have to revert that garbage, for the simple reason that
I refuse to have code in the kernel from maintainers that cannot even
understand the first rule of kernel development.

The first rule is:

 - we don't cause regressions

and the corollary is that when regressions *do* occur, we admit to
them and fix them, instead of blaming user space.

The fact that you have apparently been denying the regression now for
three weeks means that I will revert, and I will stop pulling apparmor
requests until the people involved understand how kernel development
is done.
