The 4.0 final release is in rawhide and submitted for an update for
Fedora 22 now. Given the release schedules for 4.1 and F22, we're
going to stick with 4.0 for F22 GA. Please stick to fixes for F22 and
we'll no longer keep that branch in sync with rawhide.
The 4.1 merge window is open and active upstream as well. I'll be
rebasing rawhide to those kernels likely later today or tomorrow. If
you have things that are landing in 4.1 that you'd like enabled,
please let us know. The only major feature I'm aware of that might
land is kdbus, but the jury is still out on that one.
