  cgroup: Fix race condition at rebind_subsystems() (2022-08-23 08:11:06 -1000)

----------------------------------------------------------------
cgroup fixes for v6.0-rc2

Contains fixes for the following issues:

* psi data structure was changed to be allocated dynamically but it wasn't
  being cleared leading to reporting garbage values and triggering spurious
  oom kills.

* A deadlock involving cpuset and cpu hotplug.

* When a controller is moved across cgroup hierarchies, css->rstat_css_node
  didn't get RCU drained properly from the previous list.

----------------------------------------------------------------

      sched/psi: Remove redundant cgroup_psi() when !CONFIG_CGROUPS
