For example: - -struct foo { - int stuff; - struct boo entry[]; -}; - -size = sizeof(struct foo) + count * sizeof(struct boo); -instance = kzalloc(size, 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) - -Notice that, in this case, variable reqsz is not necessary, -hence it is removed. - -This code was detected with the help of Coccinelle. - -Signed-off-by: Gustavo A.
