Hmmm... Maybe lets have
unsigned kmem_estimate_pages(struct kmem_cache *slab_cache, int objects)
which would calculate the worst case memory scenario for allocation the
number of indicated objects?
IIRC this looks more or less what Peter had initially. I don't like the
API because there's no way for slab (perhaps this is different for slub)
how many pages you really need due to per-node and per-cpu caches, etc.
It's better that the slab tells you what it actually knows and lets the
callers figure out what a worst-case upper bound is.
