From 92c6741bd6a1c5b0200c4e5695866c3dff0f8e40 Mon Sep 17 00:00:00 2001 From: Nicholas Bellinger Date: Fri, 30 Jan 2015 22:17:24 +0000 Subject: vhost-scsi: Add missing virtio-scsi -> TCM attribute conversion commit 46243860806bdc2756f3ce8ac86b4d7c616bcd6c upstream. While looking at hch's recent conversion to drop the MSG_*_TAG definitions, I noticed a long standing bug in vhost-scsi where the VIRTIO_SCSI_S_* attribute definitions where incorrectly being passed directly into target_submit_cmd_map_sgls(). This patch adds the missing virtio-scsi to TCM/SAM task attribute conversion. Cc: Christoph Hellwig Cc: Michael S.
