Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes, in particular in the context in which this code is being used. So, replace code of the following form: sizeof(*ce_hdr) + CE_COUNT * sizeof(ce_hdr->entries[0]) with: struct_size(ce_hdr, entries, CE_COUNT) This code was detected with the help of Coccinelle.
