This really looks like a brand new feature wanting to be backported, so
why does it qualify under the stable kernel rules as fixing something?
I am willing to take some kinds of "fixes performance issues" new
features when the subsystem maintainers agree and ask for it, but that
doesn't seem to be the case here, and so without their approval and
agreement that this is relevant, we can't accept them.
