I'm researching a problem with data corruption on linux 2.6.9.
I'm seeing results of scsi_print_sense() in the system log, which brought me
to this chunk of code. Is it correct to process a non-zero result with
NO_SENSE as if an error didn't occur or was recovered?

if (driver_byte(result) != 0 && /* An error occurred */

switch (SCpnt->sense_buffer[2]) {
......deleted some case statement code
case RECOVERED_ERROR: /* an error occurred, but it recovered */
case NO_SENSE: /* LLDD got sense data */

scsi_print_sense("sd", SCpnt);
SCpnt->result = 0;
SCpnt->sense_buffer[0] = 0x0;
good_bytes = this_count;
break;
