[Qemu-block] [PATCH] scsi-disk: fix reads from scsi-disk devices

From: Mark Cave-Ayland
Subject: [Qemu-block] [PATCH] scsi-disk: fix reads from scsi-disk devices
Date: Fri, 3 Jun 2016 06:17:01 +0100

Commit fcaafb1001b9c42817714dd3b2aadcfdb997b53d accidentally broke reads from
scsi-disk devices when being updated from its original form to use the new
byte-based block functions. Add the extra missing sector to offset conversion
in order to restore read functionality.
