+Subject: [PATCH] Do not try to normalize size for zero size device factories
+
+Factories with zero size are special cases for adjusting container
+size after removing a device for it. We don't want to change size
+of the factory in this case.
+The recent change of filesystem minimal size to 2 MiB resulted
+in changing of size of these factories from 0 to 2 MiB which
+caused the "adjusting factory" to create a new LV after removing
+one from the container.
