We use tcm_loop with tape emulations running on tcmu. In case application reads a short tape block with a longer READ, or a long tape block with a short READ, according to SCC spec data has to be tranferred _and_ sensebytes with ILI set and information field containing the residual count. Similar problem also exists when using fixed block size in READ. Up to now tcm_loop is not prepared to handle sensebytes if input data is provided, as in tcm_loop_queue_data_in() it only sets SAM_STAT_GOOD and, if necessary, the residual count. To fix the bug, the same handling for sensebytes as present in tcm_loop_queue_status() must be done in tcm_loop_queue_data_in() also. After adding this handling, the two function now are nearly identical, so I created a single function with two wrappers.
