This is simple xfs rootfs and then trigger swapping.

Also, the reverting is ONLY to revert your patch on the top of linux-next will stop the splat, so there is no not testing the same kernel at all. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
