+Subject: [PATCH] multipathd: fix null pointer dereference in uev_update_path
+
+The Auto-resize code added a check that deferences pp->mpp without
+checking that it's non-NULL. Fix it.

+Subject: [PATCH] multipathd: fix auto-resize configuration
+
+The code acted like AUTO_RESIZE_UNDEFINED didn't exist, but since
+conf->auto_resize was never set to AUTO_RESIZE_NEVER, the default was in
+fact AUTO_RESIZE_UNDEFINED, which ended up getting treated like
+AUTO_RESIZE_GROW_SHRINK. Remove AUTO_RESIZE_UNDEFINED and explicitly
+default auto_resize tp AUTO_RESIZE_NEVER.
