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.
