I just started to explore potential options of backporting USB subsystems. Currently I'm not at the point where I'm ready to backport drivers. I'll work on that later. >> The next question you have which you have not asked me yet is how do you >address >> cherry picks or patches not upstream.

Patches welcomed. Well, I actually didn't have that question in mind. :) I read the README files in these folders and I totally agree that there should not be patches under these 3 folders. I think compat-wireless should just fulfill the function of backporting a driver from a (stable) kernel to an old kernel. Not adding additional patches. Driver developers should strive to make important patches into the stable releases. > >BTW one idea I have as of recent is to consider using Hudson for automatic >build testing for compat-wireless but haven't yet mucked with it.
