+Subject: [PATCH] monitor: Avoid segfault when calling NULL get_bad_blocks
+
+Not all struct superswitch implement a get_bad_blocks() function,
+yet mdmon seems to call it without checking for NULL and thus
+occasionally segfaults in the test 10ddf-geometry.
+
+Fix this by checking for NULL before calling it.
