Why is patch 4/19 the only one marked for stable backports? That feels
really wrong as that will not show up until after 6.19-rc1 is out, AND
the dependant patches will also not be backported.

Please split up patch series to have "things that must be merged now"
separate from "these are for the next -rc1 release"

thanks,
