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 ioat_dca_priv { ... struct ioat_dca_slot req_slots[0]; }; Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes. So, replace the following form: sizeof(*ioatdca) + (sizeof(struct ioat_dca_slot) * slots) with: struct_size(ioatdca, req_slots, slots) This code was detected with the help of Coccinelle.
