__scsi_device_lookup(9)
NAME
__scsi_device_lookup_by_target - find a device given the target
(UNLOCKED)
SYNOPSIS
struct scsi_device *
__scsi_device_lookup_by_target(struct scsi_target * starget,
uint lun);
ARGUMENTS
- starget
- SCSI target pointer
- lun
- SCSI Logical Unit Number
DESCRIPTION
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 hostīs host_lock over this call and any access to the
returned scsi_device.
NOTE
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.
