Subject: [PATCH 22/27] DDF: getinfo_super_ddf_bvd: lba_offset calculation for RAID10
Date: Wed, 3 Jul 2013 22:28:02 +0200 [thread overview]
Message-ID: <1372883287-8859-23-git-send-email-mwilck@arcor.de> (raw)
In-Reply-To: <1372883287-8859-1-git-send-email-mwilck@arcor.de>
Secondary RAID needs some extra logic here, too.
