+Subject: [PATCH] super1: Clear memory allocated for superblock + bitmap before
+ use
+
+load_super1() did not clear memory allocated for the superblock +
+bitmap. This causes issues if the superblock does not contain a bitmap
+as later checks of bitmap features would rely on the bits being
+cleared.
+
+This bug has been around for a long time, but was only exposed in
+mdadm-3.4 with the introduction of the clustering code.
