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.

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.
