Hmm, I'm not sure I understand why struct kmem_cache_cpu ->freelist is
never scanned. For SMP, I suppose kmemleak doesn't scan the per-CPU
areas? But for UP, struct kmem_cache is allocated with kmalloc() and
that contains struct kmem_cache_cpu as well.

And I suppose we never scan struct pages either. Otherwise ->freelist
there would be a problem as well.
