- * Function:    scsi_do_req
- *
- * Purpose:     Queue a SCSI request
- *
- * Arguments:   sreq	  - command descriptor.
- *              cmnd      - actual SCSI command to be performed.
- *              buffer    - data buffer.
- *              bufflen   - size of data buffer.
- *              done      - completion function to be run.
- *              timeout   - how long to let it run before timeout.
- *              retries   - number of retries we allow.
- *
- * Lock status: No locks held upon entry.
- *
- * Returns:     Nothing.
- *
- * Notes:	This function is only used for queueing requests for things
- *		like ioctls and character device requests - this is because
- *		we essentially just inject a request into the queue for the
- *		device.
- *
- *		In order to support the scsi_device_quiesce function, we
- *		now inject requests on the *head* of the device queue
- *		rather than the tail.
