Enforce that domain isolated CPUs stay in root or isolated partitions and fail if isolated+nohz_full would leave no housekeeping CPU. Fix sched/deadline root domain handling during CPU hot-unplug and race for tasks in attaching cpusets. - Misc fixes including memory reclaim protection documentation and selftest KTAP conformance. ---------------------------------------------------------------- Bert Karwatzki (1): cgroup: include missing header for struct irq_work Chen Ridong (4): cpuset: simplify node setting on error cpuset: remove global remote_children list cpuset: remove need_rebuild_sched_domains cpuset: Treat cpusets in attaching as populated Gabriele Monaco (1): cgroup/cpuset: Rename update_unbound_workqueue_cpumask() to update_isolation_cpumasks() Guopeng Zhang (1): selftests/cgroup: conform test to KTAP format output Michal Koutný (3): docs: cgroup: Explain reclaim protection target docs: cgroup: Note about sibling relative reclaim protection docs: cgroup: No special handling of unpopulated memcgs Pingfan Liu (2): cgroup/cpuset: Introduce cpuset_cpus_allowed_locked() sched/deadline: Walk up cpuset hierarchy to decide root domain when hot-unplug Tejun Heo (4): cgroup: Rename cgroup lifecycle hooks to cgroup_task_*() cgroup: Move dying_tasks cleanup from cgroup_task_release() to cgroup_task_free() cgroup: Defer task cgroup unlink until after the task is done switching out cgroup: Fix sleeping from invalid context warning on PREEMPT_RT Waiman Long (5): cgroup/cpuset: Don't track # of local child partitions cgroup/cpuset: Fail if isolated and nohz_full don't leave any housekeeping cgroup/cpuset: Move up prstate_housekeeping_conflict() helper cgroup/cpuset: Ensure domain isolated CPUs stay in root or isolated partition cgroup/cpuset: Globally track isolated_cpus update Documentation/admin-guide/cgroup-v2.rst | 31 +- include/linux/cgroup.h | 14 +- include/linux/cpuset.h | 9 +- include/linux/sched.h | 5 +- kernel/cgroup/cgroup.c | 91 +++++- kernel/cgroup/cpuset-internal.h | 13 +- kernel/cgroup/cpuset.c | 356 ++++++++++++++--------- kernel/exit.c | 4 +- kernel/fork.c | 2 +- kernel/sched/autogroup.c | 4 +- kernel/sched/core.c | 2 + kernel/sched/deadline.c | 54 +++- tools/testing/selftests/cgroup/test_core.c | 7 +- tools/testing/selftests/cgroup/test_cpu.c | 7 +- tools/testing/selftests/cgroup/test_cpuset.c | 7 +- tools/testing/selftests/cgroup/test_freezer.c | 7 +- tools/testing/selftests/cgroup/test_kill.c | 7 +- tools/testing/selftests/cgroup/test_kmem.c | 7 +- tools/testing/selftests/cgroup/test_memcontrol.c | 7 +- tools/testing/selftests/cgroup/test_zswap.c | 7 +- 20 files changed, 435 insertions(+), 206 deletions(-) Thanks. -- tejun
