ata_scsi_translate

Name

ata_scsi_translate -- Translate then issue SCSI command to ATA device

Synopsis

void ata_scsi_translate (struct ata_port * ap, struct ata_device * dev, struct scsi_cmnd * cmd, void (*done) (struct scsi_cmnd *), ata_xlat_func_t xlat_func);

Arguments

ap: ATA port to which the command is addressed
dev: ATA device to which the command is addressed
cmd: SCSI command to execute
done: SCSI command completion function
xlat_func: -- undescribed --

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.

LOCKING

spin_lock_irqsave(host_set lock)
