That is correct. But more coffee is always good.

That's fine.

I hate and despise and complain endlessly about how you all are doing
this, but I have learned to just suck it up and accept it. It is a
major pain in the rear, and I will say that it causes me to delay all
merges of stable drm patches that get merged in Linus's tree in -rc1
until -rc2 or -rc3 is out usually as I have to go through and
hand-determine if a reject happens because it really is a reject, or
because this patch is already in the tree.
So, if this hits Linus's tree "like normal", my scripts will pick it up
and all is good. I can handle this crazy notation you all feel that
works for you, but I reserve the right to complain.
This original patch, however, was sent only to stable and it seemed to
indicate that I needed to pick it up because it already was upstream (I
saw the cherry-pick line.) As that is not the case here, fine, no harm,
no foul, let's go get more coffee...
