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.
