Subject: Re: [patch -mm v2] cpusets: add memory_slab_hardwall flag

If the nodes are exclusive to a load then the cpus attached to those nodes
are also exclusive? If so then there is no problem since the percpu queues
are only in use for a specific load with a consistent restriction on
cpusets and a consistent memory policy. Thus there is no need for
memory_slab_hardwall.
