Man page 9 : __scsi_device_lookup_by_target

__scsi_device_lookup_by_target - find a device given the target (UNLOCKED)

struct scsi_device * __scsi_device_lookup_by_target(struct scsi_target *  starget , uint  lun );

starget
    SCSI target pointer

lun
    SCSI Logical Unit Number

Looks up the scsi_device with the specified lun for a given starget. The returned scsi_device does not have an additional reference. You must hold the hostAqs host_lock over this call and any access to the returned scsi_device. A scsi_device in state SDEV_DEL is skipped.

The only reason why drivers should use this is because they need to access the device list in irq context. Otherwise you really want to use scsi_device_lookup_by_target instead.
