Name

__scsi_device_lookup — find a device given the host (UNLOCKED)

Synopsis

struct scsi_device * __scsi_device_lookup (struct Scsi_Host * shost,
 uint channel,
 uint id,
 uint lun);
 

Arguments

shost

SCSI host pointer

channel

SCSI channel (zero if only one channel)

id

SCSI target number (physical unit number)

lun

SCSI Logical Unit Number

Description

Looks up the scsi_device with the specified channel, id, lun for a given host. 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 would want to use this is because they need to access the device list in irq context. Otherwise you really want to use scsi_device_lookup instead.
