early_kmem_cache_node_alloc

Name:No kmalloc_node yet so do it by hand. We know that this is the first* slab on the node for this slabcache. There are no concurrent accesses* possible.* Note that this function only works on the kmem_cache_node* when allocating for the kmem_cache_node

Proto:static void early_kmem_cache_node_alloc(int node)

Type:void

Parameter:

int	node
