Subject: [PATCH V2 7/8] drivers: scsi: storvsc: Set srb_flags in all cases
Date: Wed,  9 Jul 2014 23:33:51 -0700	[thread overview]
Message-ID: <1404974032-5023-7-git-send-email-kys@microsoft.com> (raw)
In-Reply-To: <1404974032-5023-1-git-send-email-kys@microsoft.com>

Correctly set SRB flags for all valid I/O directions. Some IHV drivers on the
Windows host require this.
