Oof. That's ugly. Particularly ugly in that it could actually share the
attr with the root cache, except for the name.
We could put a char * in the kmem_cache which (if not NULL) overrides
the attr->name? Probably want a helper to replace the endearingly short
's->name'. Something like:
#define slab_name(s) s->name ?: s->attr->name
