Just because Facebook is working on btrfs in their OS, doesn't mean they will publish their code and patches to the public.

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.

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.
