There are probably better places to spend your time! If you want 'security' for kmalloc() then: #define KMALLOC_TYPE(flags) (type *)kmalloc(sizeof (type), flags) #define KMALLOC(ptr, flags) *(ptr) = KMALLOC_TYPE(typeof *(ptr), flags) and change: ptr = kmalloc(sizeof *ptr, flags); to: KMALLOC(&ptr, flags); But it is all churn for churn's sake.
