+Subject: [PATCH] mdadm: Fix optional --write-behind parameter
+
+The commit noted below changed the behaviour of --write-behind to
+require an argument. This broke the 06wrmostly test with the error:
+
+  mdadm: Invalid value for maximum outstanding write-behind writes: (null).
+         Must be between 0 and 16383.
+
+To fix this, check if optarg is NULL before parising it, as the origial
+code did.
+
+Upstream-Status: Backport [https://git.kernel.org/pub/scm/utils/mdadm/mdadm.git/commit/?id=41edf6f45895193f4a523cb0a08d639c9ff9ccc9]

+Fixes: 60815698c0ac ("Refactor parse_num and use it to parse optarg.")
