I will take care to address the feedback from Tomas and Jason but won't
yet try to push this into v4.21. It is a patch set, which is better to
lie in linux-next before landing to a release. Probably will push the
patches soon after my v4.21 PR to linux-next. Then they will get maximum
time of exposure.
