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.
