Hi,
We have a bug report where sched_setaffinity fails for cpus that are
hotplug added after boot. Nathan found this suspicious piece of code:
void __init cpuset_init_smp(void)
{
top_cpuset.cpus_allowed = cpu_online_map;
top_cpuset.mems_allowed = node_online_map;
}
Any reason we statically set the top level cpuset to the boot time cpu
online map?
