What's the benefit of using kmalloc_array instead of just kmalloc?
It has built in integer overflow protection. Whenever I see multiplication in kmalloc(), I automatically start to audit for overflows, but now, ha ha, just change it to kmalloc_array() and forget about it. (There weren't any integer overflow problems in the original code, btw).
