You need to do this for slub_max_order not for slub_min_order. Also the
slub_max_order may not necessarily be used. It is just the maximum allowed
order. I could maintain a slub_max_used_order variable. When that is
increased I could call raise_kswapd_order?
The same call needs to be put into kmem_cache_init? Or is this only for
orders > 3?
