Lol what? We don't ship code that isn't upstream. It sucks to maintain and rebase if you have a shitton of proprietary patches. Everything we do with the kernel is open source, you wouldn't be able to hire kernel developers if you didn't do open source. Nice comment tho, I legitimately lol'ed.
Just because some code is added to the main kernel, assuming it is, doesn't mean it will be propagated to the main LTS distributions anytime soon.
