Subject: [PATCH 2/2] cciss: fix flush cache transfer length
Date: Mon, 28 Nov 2011 10:14:48 -0600 [thread overview]
Message-ID: <20111128161448.25472.60872.stgit@beardog.cce.hp.com> (raw)
In-Reply-To: <20111128161442.25472.71410.stgit@beardog.cce.hp.com>
From: Stephen M. Cameron <scameron@beardog.cce.hp.com>
We weren't filling in the transfer length of the
flush cache command (it transfers 4 bytes of zeroes).
Firmware didn't seem to be bothered by this, but it
should be fixed.
