- Defer task cgroup unlink until after the dying task's final context switch
so that controllers see the cgroup properly populated until the task is
truly gone.
- cpuset cleanups and simplifications. 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.
