For an ATA device supporting the sense data reporting feature set, a failed command will trigger the execution of ata_eh_request_sense if the result task file of the failed command has the ATA_SENSE bit set (sense data available bit). ata_eh_request_sense executes the REQUEST SENSE DATA EXT command to retrieve the sense data of the failed command. On success of REQUEST SENSE DATA EXT, the ATA_SENSE bit will NOT be set (the command succeeded) but ata_eh_request_sense nevertheless tests the availability of sense data by testing that bit presence in the result tf of the REQUEST SENSE DATA EXT command. This leads to a falsy assume that request sense data failed and to the
False assumption?
