I'd like to say "the community", and that means anybody who wants to
interact on this topic. I will probably be the guy who eventually
applies the patch(es).

We only bring support to the latest mainline kernel, whatever version
it could be. So if you send a patch (please follow the contributing
guidelines in Documentation/) it should be a diff against the next -rc1
(so it will be v6.8-rc1 in two weeks). You can share diffs for other
versions as well on your own website but there is usually no backport
of 'new features'.

If it compiles, it will probably work as well as the core has not
changed much since it's been created, but there is of course no
guarantee.

Thanks,
Miquèl
