Re: [Libguestfs] [PATCH libnbd v3 1/6] lib/opt: Don't use NULL for an empty StringList

OK now I remember what the problem was. In this original code you're calling the internal unlocked version of nbd_opt_set_meta_context_queries. However the generator is creating a prototype for the unlocked function and it adds the attribute((nonnull)) annotation for it, something like: extern int nbd_unlocked_opt_set_meta_context_queries (...) LIBNBD_ATTRIBUTE_NONNULL((1, 2)); This means that you cannot use queries == NULL here. I think the generated annotation is correct, but we need a new unannotated internal function that allows queries == NULL. I'll try to come up with something.
