Christ. Heard about that thing called "backwards compatibility"? We *require* that those "future kernels" run the old unmodified binaries. Yeah, I know you don't have that requirement, but anything that actually wants to be considered *relevant* and actually merged into a mainline kernel does have that requirement. So your argument is utter crap, ignorant, and stupid. No, we don't update any libraries for a kernel upgrade. Ever. End of story. Linus
