Hi Bart

I have not changed the configuration in LIO target though.
The /etc/target json file is the same as always and Its been like this
for years

I just rebooted the server into 4.13 and its fine again and found all
the targets with the same kernel on the client.

So its specific to your new tree with srpt

I will reboot again and re-load LIO and show you but here is my ACL
list that has been this way for some time.
