ata_scsi_find_dev: lookup ata_device from scsi_cmnd
ata_scsi_find_dev - lookup ata_device from scsi_cmnd
struct ata_device * ata_scsi_find_dev(struct ata_port
*ap, const struct scsi_device *scsidev);
- ATA port to which the device is attached
- SCSI device from which we derive the ATA device
Given various information provided in struct scsi_cmnd, map that onto an ATA bus, and using that mapping determine which ata_device is associated with the SCSI command to be sent.
