Subject: [PATCH 04/41] hpsa: rename scsi prefetch field
Date: Wed, 15 Jan 2014 16:36:38 -0600 [thread overview]
Message-ID: <20140115223638.5061.40768.stgit@beardog.cce.hp.com> (raw)
In-Reply-To: <20140115223354.5061.50276.stgit@beardog.cce.hp.com>
From: Stephen M. Cameron <scameron@beardog.cce.hp.com>
The field contains more bits than just the one
to indicate whether scsi prefetch should be turned on.
