torture_percpu_rwsem_down_write | |
cgroup_procs_write_start | |
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. |
