I suspect there are more, but there's no need for us to be thorough at this point. > --- a/range-diff.c > +++ b/range-diff.c > @@ -232,11 +232,9 @@ static int patch_util_cmp(const void *dummy, const struct patch_util *a, > > static void find_exact_matches(struct string_list *a, struct string_list *b) > { > - struct hashmap map; > + struct hashmap map = HASHMAP_INIT((hashmap_cmp_fn)patch_util_cmp, NULL); Not related to your patch, but we should in general try to define these comparison functions with the correct signature, rather than cast them. I think I've already inflated your series enough, so let's leave it for now, but just a mental note that it might be useful to circle back and fix these en masse (I know we cleaned up several a while back, so I'm actually surprised to see one still here). -Peff
