    We've referred to this for quite a while as the "ABI header project";
    it's been targetted for 2.7, since it missed the 2.6 freeze.

    We have set up a mailing list at:

            http://zytor.com/mailman/listinfo/linuxabi

    The goal is to get a formal exportable version of the kernel ABI that
    user-space libraries can use.
