Subject: [PATCH v3 11/12] virtio_scsi: Remove code that zeroes driver-private command data
Date: Fri, 2 Jun 2017 14:22:02 -0700	[thread overview]
Message-ID: <20170602212203.30401-12-bart.vanassche@sandisk.com> (raw)
In-Reply-To: <20170602212203.30401-1-bart.vanassche@sandisk.com>

Since the SCSI core zeroes driver-private command data, remove
that code from the virtio driver.
