Hey, I already told this thing. If CONFIG_HIGHMEM=n, N_HIGH_MEMORY and N_NORMAL_MEMORY are share the same value. then, node_set_state(nid, N_HIGH_MEMORY) in free_area_init_nodes() mean set both N_HIGH_MEMORY and N_NORMAL_MEMORY. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxxx For more info on Linux MM, see: http://www.linux-mm.org/ .
