1. NAME

__scsi_device_lookup - find a device given the host (UNLOCKED)

2. SYNOPSIS

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

3. 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

4. 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 hostAqs host_lock over this call and any access to the returned scsi_device.

5. 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.
