Hi .=20 Yes . =20 2df3bae9a6543e90042291707b8db0cbfbae9ee9 Needs refactored to work in 4.14.y (now .190) as there is a conflict in = arguments as noted in my original submittal ;-) .=20 I also noticed there are warning to functions " defined but not used = [-Wunused-function] =E2=80=9C 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. =20
