    Well, it's a historical fact that ksize() worked for both kmalloc()
    and kmem_cache_alloc() (see the kernedoc comment in mm/slab.c).
    However, I think we should just look at getting rid of ksize()
    altogether as it's only (ab)used by the nommu code and few call-sites
    that open-code krealloc().
