mdadm and superblock format > 1

[Michal Soltys]

I've noticed, that whenever I use 1.1 or 1.2 superblock format, mdadm 
will always report version 1, when i.e. mdadm -E --scan is issued.

Also, in these two cases, mdadm -A --scan won't work, unless proper 
ARRAY line is present in mdadm.conf (and if metadata is part of the 
description, it must be either 1.1 or 1.2).

This is fixed in the current git repository.  It will be in the next
release whenever I get around to making one.

This is that patch that fixes it.
