My thinking was that it is a reasonably self contained patch (most of
the code is the new files) and without it people won't be able to use
4.1.x with their distro kernels at all, so it's something between a bug
fix and a new feature.

If distros are going to be backporting it anyway they may as well all
get it from us.
