Subject: [PATCH 37/83] 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.
|
|
|
|
Fixes: 60815698c0ac ("Refactor parse_num and use it to parse optarg.")
