    afs: Use struct_size() in kzalloc() · c2b8bd49
    Gustavo A. R. Silva authored
    One of the more common cases of allocation size calculations is finding the
    size of a structure that has a zero-sized array at the end, along with
    memory for some number of elements for that array. For example:
    struct foo {
        int stuff;
        void *entry[];
    instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);
    Instead of leaving these open-coded and prone to type mistakes, we can now
    use the new struct_size() helper:
    instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);
    This code was detected with the help of Coccinelle.
