Being aware is different than saying it was snuck in without anyone

Okay, let's take mm/ as a subsystem that is doing a good job with
submitting stuff to -stable.

There were 40 patches in total going into the 4.14 LTS tree that touched
mm/. Out of those, 5 were selected via the "automagic" process:

The only "questionable" one here I see is the performance regression
one, which I decided to keep in because it's a rather severe one in a
common code path.

Even good subsystems might sometimes miss a patch or two.

But yes, I've received less response from maintainers than I expected,
so I'll switch it to an opt-in model for new patches that go upstream.
