It would be nice to include this patch, all the major distros include it anyway. Also gentoo has gdm, systemd and openrc with plymouth support it would be great if the last missing piece to have a smooth transition.
What is the upstream status of this patch?
Honestly i don't know but for a few years the major distros ship this patch, eventualy it will end up there.
I am asking about upstream because we don't want to be stuck with maintaining such a patch indefinitely. It would be good if you send this patch to the intel-gfx mailing list to get at least a comment from the developers.
