    Shouldn't getting/putting the module refcount be solely done in
    kobject.c? Grab the module reference when the kobject is created and
    release the module reference in kobject_cleanup() after the release
    function has been called. This doesn't make kobject_get() heavier, and
    it ensures we don't delete the module until after the last kobject it is
    supposed to clean up has been released.
