It's trying to fix 2 issues caused by the following script which
connect/disconnect rnbd frequently.

# cat rnbd-self.sh 
#!/bin/bash

/root/rpma/tools/config_softroce.sh eth0
modprobe rnbd_server
modprobe rnbd_client

while true;
do
        echo "sessname=xyz path=ip:<server-ip> device_path=/dev/nvme0n1" > /sys/devices/virtual/rnbd-client/ctl/map_device
        for i in /sys/block/rnbd*/rnbd/unmap_device
        do
                echo "normal" > $i
        done
done
