Prototype was for __alloc_size() instead Yay kerndoc. Thanks for catching this, and I realize Matthew Wilcox predicted this earlier: https://lore.kernel.org/lkml/3a0c55a3fabc57ce9771c93499ef19327f3b8621.camel@xxxxxxxxxxx/ I will get a fix sent. -Kees > include/linux/slab.h:623: warning: Function parameter or member '1' not described in '__alloc_size' > include/linux/slab.h:623: warning: Function parameter or member '2' not described in '__alloc_size' > include/linux/slab.h:623: warning: expecting prototype for kmalloc_array().
