At this state, there are three get_submodule_ref_store() callers: - for_each_remote_ref_submodule() - handle_revision_pseudo_opt() - resolve_gitlink_ref() The first two deal explicitly with submodules (and we should never fall back to the main ref store as a result). They are only called from submodule.c: - find_first_merges() - submodule_needs_pushing() - push_submodule() The last one, as its name implies, deals only with submodules too, and the "submodule" (path) argument must be a non-NULL, non-empty string. So, this "if NULL or empty string" code block should never ever trigger. And it's wrong to fall back to the main ref store anyway. Delete it.
