Subject: [PATCH 1/2] DDF: factor out array name generation
Date: Wed, 11 Sep 2013 21:55:34 +0200	[thread overview]
Message-ID: <1378929335-12606-1-git-send-email-mwilck@arcor.de> (raw)
In-Reply-To: <5230C98B.7030902@arcor.de>

The same algorithm was used in getinfo_super_ddf_bvd and
container_content_ddf. Put it in a common function.
