The error codes: DID_TARGET_FAILURE DID_NEXUS_FAILURE DID_ALLOC_FAILURE DID_MEDIUM_ERROR are internal to the SCSI layer. Drivers must not use them because: 1. They are not propagated upwards, so SG IO/passthrough users will not see an error and think a command was successful. xen-scsiback will never see this error and should not try to send it. 2. There is no handling for them in scsi_decide_disposition so if xen-scsifront were to return the error to scsi-ml then it kicks off the error handler which is definitely not what we want. This patch remove the use from xen-scsifront/back. Signed-off-by: Mike Christie <michael.christie@xxxxxxxxxx>
