Regression means something that worked in a previous version of the kernel which is broken now. This problem falls within that definition.

Because there was no co-ordination between their version of the patch and yours. If you're sending in patches that you know might break systems because they need a co-ordinated rollout of something in userspace then it would be nice if you could co-ordinate it ...
Doing it in the merge window and not in -rc2 would also be helpful because I have more expectation of a userspace mismatch from stuff in the merge window.

Well, that looks really encouraging: The line about "To give you an impression what "lots of" means - I had to adjust 40 profiles on my laptop". The upshot being apart from a bandaid, openSUSE still has no co-ordinated fix for this.
