Hi .

Yes .

2df3bae9a6543e90042291707b8db0cbfbae9ee9

Needs refactored to work in 4.14.y (now .190) as there is a conflict in arguments as noted in my original submittal ;-) .
I also noticed there are warning to functions " defined but not used [-Wunused-function] “ too.

Do you want another PATCH v2 message in a new email thread, or can I append it to this this thread ?

Please advice.

Thanks.
JD.
