it has to be divided and addressed incrementally. Ok, but then don't expect us to be able to actually review it in any sane way, sorry. Think about it from our side, what would you want to see if you had to review this type of thing? Remember, some of us get hundreds of things to review a week, we don't have context for each and every new feature, and your project does not have the "trust" in that we would even consider taking anything without any real user both in the kernel and in public userspace code. Breaking up changes in a way that is acceptable upstream is a tough task, usually harder than the original engineering effort to create the feature in the first place. But in the end, the result is a better solution as it will evolve and change along the way based on reviews and requirements from the different subsystems. good luck! greg k-h
