Subject: [PATCH 15/18] scsi: storvsc: Initialize driver-private command before using it
Date: Fri, 19 May 2017 11:30:13 -0700	[thread overview]
Message-ID: <20170519183016.12646-16-bart.vanassche@sandisk.com> (raw)
In-Reply-To: <20170519183016.12646-1-bart.vanassche@sandisk.com>

The storvsc driver is the only SCSI LLD that uses driver-private
command data and that does not zero-initialize that data before
reading it. Make this driver consistent with the other SCSI LLDs
that use driver-private command data.
