3.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Hannes Reinecke <hare@xxxxxxx> commit 6375f8908255ea7438b60bb5998e6b3e1628500d upstream. The SCSI command tag is set to the tag assigned from the block layer, not the SCSI-II tag message. So we need to convert it into the correct SCSI-II tag message based on the device flags, not the tag value itself.
