The Linux kernel development moves at a fairly rapid pace, and sadly it's not practical to have fully supported backwards compatibility in a community effort such as CAKE. Now, this doesn't mean that we won't take patches to fix things for old kernels; or even help with debugging on old versions, as you've already seen in this thread. But the reality is unfortunately that the bulk of this effort is going to have to be on the users running on those kernels. I.e., you in this case. Such is open source: everyone scratches their own itch and the end result is something that (mostly) works for everyone :) -Toke
