Our current memeory allocation routines suffer form an API imbalance, for one we have kmalloc_array() and kcalloc() which check for overflows in size multiplication and we have kmalloc_node() and kzalloc_node() which allow for memory allocation on a certain NUMA node but don't check for eventual overflows.
