Hi Tejun, Could you pick up those bug fixes? Or should I ask Ingo/akpm to take care of them? On 2015/2/13 11:19, Zefan Li wrote: > If clone_children is enabled, effective masks won't be initialized > due to the bug: > > # mount -t cgroup -o cpuset xxx /mnt > # echo 1 > cgroup.clone_children

From: Jason Low The cpuset.sched_relax_domain_level can control how far we do immediate load balancing on a system. However, it was found on recent kernels that echo'ing a value into cpuset.sched_relax_domain_level did not reduce any immediate load balancing. The reason this occurred was because

If clone_children is enabled, effective masks won't be initialized due to the bug: # mount -t cgroup -o cpuset xxx /mnt # echo 1 > cgroup.clone_children # mkdir /mnt/tmp # cat /mnt/tmp/ # cat cpuset.effective_cpus # cat cpuset.cpus 0-15 And then this cpuset won't constrain the task
