Subject: [PATCH 7/7] megaraid: fix transfer length 0 for 6-byte r/w commands
Date: Sat, 16 May 2015 16:17:53 +0900 [thread overview]
Message-ID: <1431760673-7180-8-git-send-email-akinobu.mita@gmail.com> (raw)
In-Reply-To: <1431760673-7180-1-git-send-email-akinobu.mita@gmail.com>
For 6-byte r/w commands, transfer length 0 means 256 blocks of data,
not 0 block.
