( a cpuset is a mandatory container for set_cpus_allowed(), so there is a material and app-visible difference between a 4-CPU cpuset that has balancing disabled and 4x 1-CPU cpusets. ) Ingo - 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/ | ||||||||||||
