There seems to be a lot of confusion [1] about which options to set or not set, so it would be nice if anyone could give the exact ones. > To switch off group scheduling completely, please set CONFIG_GROUP_SCHED to off. If you wish to have cgroup based group scheduling, you need to set CONFIG_CGROUP_SCHED on (and if required CONFIG_FAIR_GROUP_SCHED for CFS group scheduling and CONFIG_RT_GROUP_SCHED for RT group scheduling) -- regards, Dhaval -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
