If distros want to "camp out" on an old kernel version, that's fine, as
I describe in:
	http://www.kroah.com/log/blog/2018/08/24/what-stable-kernel-should-i-use/
many years ago.

But for someone using a device where they want to use "new" hardware,
that was made _after_ the kernel version was released, that's just
someone who needs to pick a better distro :)
