Actually we thought that there could be a race between openers due to which disk_openers could be more than 1 and due to which the Lo_rundown cannot be set. Hence LTP test could fail. But if I understand correctly, I think the LTP test is meant to run separately without any other processes opening the loop device. I will send the next version with the change which sets rundown when there is just a single opener.
