NAME
       scsi_adjust_queue_depth - Let low level drivers change a device's queue depth

SYNOPSIS
       void scsi_adjust_queue_depth(struct scsi_device * sdev, int tagged, int tags);

ARGUMENTS
       sdev
	   SCSI Device in question

       tagged
	   Do we use tagged queueing (non-0) or do we treat this device as an untagged device (0)

       tags
	   Number of tags allowed if tagged queueing enabled, or number of commands the low level driver can queue up in non-tagged mode (as per
	   cmd_per_lun).

RETURNS
       Nothing

LOCK STATUS
       None held on entry

NOTES
       Low level drivers may call this at any time and we will do the right thing depending on whether or not the device is currently active and
       whether or not it even has the command blocks built yet.
