22 Looks up the scsi_device with the specified lun for a given starget.
23 The returned scsi_device does not have an additional reference. You
24 must hold the host's host_lock over this call and any access to the
25 returned scsi_device. A scsi_device in state SDEV_DEL is skipped.
26
28 The only reason why drivers should use this is because they need to
29 access the device list in irq context. Otherwise you really want to use
30 scsi_device_lookup_by_target instead.
