+Subject: [PATCH] libmultipath: move remove_map waiter code to multipathd
+
+Only multipathd needs to worry about the multipath waiter code. There is
+no point in having remove_map_and_stop_waiter() or
+remove_maps_and_stop_waiters() in libmultipath, since they should never
+be use outside of multipathd.
