Hmmmm. Could you explain what it exactly means? I can see that files_ref_store structure has the .repo member and files_ref_store_create() uses it to remember which repository the ref store is for, but that is an implementation detail that is not exposed outside the files backend, isn't it? To put it differently, what is broken with the current code that leaves the .repo member in refs->base uninitialized? We are presumably helping the caller that wants to know the repository the ref store belongs to via this pointer with this change---what is that caller?

Thanks.
