Name	Describe
validate_change	validate_change() - Used to validate that any proposed cpuset change* follows the structural rules for cpusets
update_cpumasks_hier	pdate_cpumasks_hier - Update effective cpumasks and tasks in the subtree@cs: the cpuset to consider@tmp: temp variables for calculating effective_cpus & partition setup* When congifured cpumask is changed, the effective cpumasks of this cpuset
update_nodemasks_hier	pdate_nodemasks_hier - Update effective nodemasks and tasks in the subtree@cs: the cpuset to consider@new_mems: a temp variable for calculating new effective_mems* When configured nodemask is changed, the effective nodemasks of this cpuset
cpuset_can_attach	Called by cgroups to determine if a cpuset is usable; cpuset_mutex held
cpuset_css_online
cpuset_bind
cpuset_hotplug_update_tasks	puset_hotplug_update_tasks - update tasks in a cpuset for hotunplug@cs: cpuset in interest@tmp: the tmpmasks structure pointer* Compare @cs's cpu and mem masks against top_cpuset and if some have gone* offline, update @cs accordingly
cpuset_hotplug_workfn	CPU / memory hotplug is handled asynchronously.
cpuset_cpus_allowed_fallback	puset_cpus_allowed_fallback - final fallback before complete catastrophe
