ata_scsi_translate - Translate then issue SCSI command to ATA device
2. SYNOPSIS ▲
int ata_scsi_translate(struct ata_device * dev , struct scsi_cmnd * cmd , ata_xlat_func_t xlat_func );
3. ARGUMENTS ▲
ATA device to which the command is addressed
SCSI command to execute
Actor which translates cmd to an ATA taskfile
4. DESCRIPTION ▲
Our ->queuecommand function has decided that the SCSI command issued can be directly translated into an ATA command, rather than handled internally.
This function sets up an ata_queued_cmd structure for the SCSI command, and sends that ata_queued_cmd to the hardware.
The xlat_func argument (actor) returns 0 if ready to execute ATA command, else 1 to finish translation. If 1 is returned then cmd->result (and possibly cmd->sense_buffer) are assumed to be set reflecting an error condition or clean (early) termination.
5. LOCKING ▲
6. RETURNS ▲
0 on success, SCSI_ML_QUEUE_DEVICE_BUSY if the command needs to be deferred.
