The slabs_node() always return zero when CONFIG_SLUB_DEBUG is disabled. But some codes determine whether slab is empty by checking the return value of slabs_node(). As you know, the result is not correct. we move the nr_slabs of kmem_cache_node out of the CONFIG_SLUB_DEBUG. So we can get the corrent value returned by the slabs_node().
