Because that's a function for kernel modules to use--Linus doesn't
believe in stable APIs for drivers. They're supposed to be submitted to
mainline, where they can be taken care of in public.
Take a look in the kernel sources at "Documentation/stable_api_nonsense.txt"
ps. Try asking linux-kernel at vger.kernel.org if you are thick-skinned.
