__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, u64 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.
