But the patch is most horrible.. :/ It completely destroys everything group scheduling is supposed to be. What are these oink/pert things? Both spinners just with amusing names to distinguish them? Is the interactivity the same (horrible) at fe32d3cd5e8e (ie, before the load tracking rewrite from Yuyang)? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
