Subject: [PATCH 1/2] DDF: add_to_super_ddf: leave invalid secondary_lba untouched
Date: Tue, 24 Sep 2013 19:18:51 +0200	[thread overview]
Message-ID: <1380043132-8099-2-git-send-email-mwilck@arcor.de> (raw)
In-Reply-To: <1380043132-8099-1-git-send-email-mwilck@arcor.de>

If the current DDF structure doesn't have a secondary header,
don't set it.
