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.
