Turns out almost no one uses extra-long LTS kernels, so let's slowly unwind from that interesting experiment:

@gregkh Ah! Neat. What're the regulations? This is (likely good) news to me.

@gregkh This sounds weird for me: the commit log says "wind back", but the EOL dates are moved out to the future, so the support period is made longer. I thought that "wind back" meant "to reduce something that was extended too far".

@gregkh any statistics/data available showing kernels versions used out there?

@ignacio No public ones that I know of sorry. Ask your favorite Android/Cloud/Distro vendor for what they use if you are curious. Otherwise, just don't worry about it and always use the latest stable kernel releases and you will be fine.

@gregkh I see. I suppose the folks behind Ubuntu that extend support for Ubuntu 16 with kernel 4.4 until 2026 do the backporting of security patches themselves.

@ignacio I have no idea how Ubuntu does anything, go ask them how they determine what is to be added to those old and obsolete kernel versions. You're paying them for that support, so you deserve to know how it is managed. Good luck!
