Do you mean

    Log: upgrade important messages and downgrade unimportant ones

?? This commit actually increased severity for message on target node:

@@ -1180,7 +1180,7 @@ int servant(const char *diskname, int mode, const
void* argp)
                }

                if (s_mbox->cmd > 0) {
-                       cl_log(LOG_INFO,
+                       cl_log(LOG_NOTICE,
                               "Received command %s from %s on disk %s",
                               char2cmd(s_mbox->cmd), s_mbox->from,
diskname);

and did not change severity for messages on source node (they are still
INFO).
