Hello James,

Do you perhaps mean that scsi_io_completion() returns early for
REQ_TYPE_BLOCK_PC requests? Can you clarify this further?

Anyway, currently the following functions interpret the SCSI sense
buffer:
* scsi_io_completion() in scsi_lib.c.
* scsi_mode_sense() in scsi_lib.c.
* scsi_test_unit_ready_flags() in scsi_lib.c.
* scsi_probe_lun() in scsi_scan.c.
* scsi_report_lun_scan() in scsi_scan.c.
* ioctl_internal_command() in scsi_ioctl.c.
* sg_rq_end_io() in sg.c.
* scsi_check_sense() in scsi_error.c.
* spi_execute() in scsi_transport_spi.c.

Are you sure we should add sense code interpretation code in a tenth
function in the SCSI core?

Thanks,
