    That's only going to be possible if *every* utility that uses ioctl or
    /proc can somehow decide that the interface format has changed. IMHO
    it is not possible with the current interfaces. You would need to add
    an interface version identifier to ioctl structures and /proc files
    (like MODVERSIONS). The alternative is to insist that all changes be
    upwards compatible, not really feasible.

    ps. We don't want the "/proc files should have a structured format"
    thread again please.

    pps. My check_linux_requirements script has gone in to the
    Documentation/Changes maintainer, I hope it gets into the kernel.
