Why do you need 4 files here? Can't you do this all in one? There's no need for such a small driver to be split up, that just causes added complexity and makes things harder to review and understand. > include/uapi/linux/rsmu.h | 64 +++++++++++ Where are you documenting these new custom ioctls? And why do you even need them? thanks, greg k-h
