Thanks for catching this dependency. Do I assume it correctly that this is stable-4.9 only?
I have no idea how I could find it automatically that a stable patch of linus tree is spread out with several stable trees(Hope Greg has an answer). I just checked 4.4 longterm kernel and couldn't find it in there.
See http://lkml.kernel.org/r/20190115174036.GA24149@dhcp22.suse.cz
But my question was more about "this is a stable only thing"? It was not obvious from the subject so I wanted to be sure that I am not missing anything.
