I wrote a lengthy explanation of why moving tasks between cgroups is problematic from a memcg view: https://lkml.org/lkml/2014/12/19/358 Rather than creating super-cgroups as configuration domains and using migration as a reconfiguration mechanism, it's much better to group tasks per app and reconfigure the groups themselves using specific presets for classes of apps, like foreground, background, audio. -- To unsubscribe from this list: send the line "unsubscribe cgroups" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
