 cgroup: Changes for v6.19
 
 - 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.
