Subject: [PATCH 3/3] Fix incremental to not create an array, but add to
 existing

06bd679317a2a514aa7d51b54b5ad2a01742e42e disabled incremental completely.
What we really want is that mdadm should not start or create
a clustered array but still be able to add or readd to an existing
device. This would enable udev scripts to automatically add
or re-add a device after transient errors.
