Adding the kernel list on CC because this is a good question and
there's no reason to not answer a broader number of people.

Have to think about this. We tend to avoid full driver backports and
4.4.y will be released fairly soon. I don't believe 4.3 will live
very long in F23, perhaps a month at most so doing a full backport
might not be worthwhile.

Similar answer. We'd be more likely to backport it to 4.4 than 4.3.
And in both this and the above case, it would probably have to go into
rawhide and live there for a while to get some testing.

So we have no fast and hard rules, but as I said we tend to avoid full
driver backports. Feature additions to existing driver and bugfixes
are much easier to carry. In either case, the code needs to be
upstream or very clearly headed there in a not distant release. It's
probably best to think of our approach as a slightly less restrictive
version of the upstream stable process. We'll occasionally take
things from trees other than Linus' but only if it looks like it is
heading there soon anyway.
And we reserve the right to break our own approach :).

There's been some back and forth on those IIRC. Probably not worth
grabbing for 4.3 at this point.
