The cpuset pointer is found at task->cgroups->subsys[cpuset_subsys_id], where cpuset_subsys_id is a compile-time constant. Sounds reasonable. I didn't notice any performance hit on a pure allocate/free memory benchmark relative to non-cgroup cpusets. (There was a small performance hit relative to not using cpusets at all, but that was to be expected). Paul -
