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.")
