we can simplify ^this hunk a bit by applying what patch 3/4 does, so I'll
squash the following in:

--- a/src/test/test_driver.c
+++ b/src/test/test_driver.c
@@ -4096,15 +4096,8 @@ testDomainFSFreeze(virDomainPtr dom,
     priv = vm->privateData;

     if (nmountpoints == 0) {
-        ret = 0;
-        if (priv->frozen[0] == false) {
-            priv->frozen[0] = true;
-            ret++;
-        }
-        if (priv->frozen[1] == false) {
-            priv->frozen[1] = true;
-            ret++;
-        }
+        ret = 2 - (priv->frozen[0] + priv->frozen[1]);
+        priv->frozen[0] = priv->frozen[1] = true;
     } else {
         int nfreeze = 0;
         bool freeze[2];
