Ok, you all are already totally messing with my normal stable workflow, so might as well just trust you all completely. So let's just only take patches that you all do send me in the normal way. It's easy for Sasha to filter out the drm/i915 patches from his results.

Um, that is what he was doing with the cc: of you all on the patch itself that started this whole conversation... {sigh} greg k-h _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
