It > was merged into the mainline Oct 4th? It was acked by Andrew to be merged through a drm tree, since it was part of a graphics driver functionality. It was preceded by a fairly lenghty discussion on linux-mm / linux-kernel. It was merged into drm-next on 19-11-28, I think that's when it normally is seen by linux-next. Merged into mainline 19-11-30. Andrew's tree got merged 19-12-05. linux-next signaled a merge conflict from one of the patches in this series (not this one) resolved manually with the akpm tree on 19-12-02. Thomas
