    ksize does not take a kmem_cache pointer and it is mainly used for
    figuring out how much space kmalloc really allocated for an object. As
    such its more part of the kmalloc/kfree set of calls than the
    kmem_cache_* calls.

    We could add another call

    kmem_cache_size()

    for symmetries sake.
