| cgroup_procs_write_start | |
| cgroup_procs_write_finish | |
| cgroup_update_dfl_csses | group_update_dfl_csses - update css assoc of a subtree in default hierarchy*@cgrp: root of the subtree to update csses for*@cgrp's control masks have changed and its subtree's css associations* need to be updated accordingly | 
| cgroup_attach_task_all | group_attach_task_all - attach task 'tsk' to all cgroups of task 'from'*@from: attach to all cgroups of a given task*@tsk: the task to be attached | 
| cgroup_transfer_tasks | group_trasnsfer_tasks - move tasks from one cgroup to another*@to: cgroup to which the tasks will be moved*@from: cgroup in which the tasks currently reside* Locking rules between cgroup_post_fork() and the migration path* guarantee that, if a task is | 
| rebuild_sched_domains | |
| cpuset_can_attach | Called by cgroups to determine if a cpuset is usable; cpuset_mutex held | 
| cpuset_cancel_attach | |
| cpuset_attach | |
| cpuset_write_u64 | |
| cpuset_write_s64 | |
| cpuset_write_resmask | Common handling for a write to a "cpus" or "mems" file. | 
| sched_partition_write | |
| cpuset_css_online | |
| cpuset_css_offline | If the cpuset being removed has its flag 'sched_load_balance'* enabled, then simulate turning sched_load_balance off, which* will call rebuild_sched_domains_locked(). That is not needed* in the default hierarchy where only changes in partition | 
| cpuset_bind | |
| hotplug_update_tasks_legacy | |
| 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. |
