"Fixes:" are never guaranteed to show up in stable kernels, they are only a "maybe when we get some spare cycles and get around to it we might do a simple pass to see what works or doesn't." If you KNOW a change is a bugfix for stable kernels, please mark it as such! "Fixes:" is NOT how to do that, and never has been. It's only additional meta-data that helps us out. So please send us a list of the commits that need to go to 6.12.y and 6.13.y, we have to have that before we could take the 6.6.y changes. thanks, greg k-h
