__SCSI_DEVICE_LOOKUP(9) SCSI mid layer __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 host´s host_lock over this call and any access to the
returned scsi_device. A scsi_device in state SDEV_DEL is skipped.
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.
