Please do not open a new thread until a previous one reaches some
conclusion. I have outlined some ways to go forward in
http://lkml.kernel.org/r/20190515145151.GG16651@dhcp22.suse.cz.
I haven't heard any feedback on that, yet you open a 3rd way in a
different thread. This will not help to move on with the discussion.

Please follow up on that thread.
