From ba88add58176a883e4137ee9bb5e66235799a9d9 Mon Sep 17 00:00:00 2001 From: Michael Haggerty Date: Fri, 10 Feb 2017 12:16:14 +0100 Subject: [PATCH] register_ref_store(): new function Move the responsibility for registering the ref_store for a submodule from base_ref_store_init() to a new function, register_ref_store(). Call the latter from ref_store_init().
