This patch modifies existing transport_complete_*() code to avoid invoking target_core_fabric_ops->queue_data_in() driver callbacks for I/O READs with non-GOOD SAM status. Some initiators expect GOOD status when a DATA-IN payload transfer is involved, so to be safe go ahead and always invoke target_core_fabric_ops->queue_status() to generate fabric responses instead. Note this is a prerequisite for IBLOCK supporting retriable status, so SAM_STAT_BUSY + SAM_STAT_TASK_SET_FULL always generates fabric driver responses instead of initiating DataIN payload transfer when non-GOOD status is present Reviewed-by:
