Merge tag 'cgroup-for-6.0-rc2-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup fixes from Tejun Heo:
- The psi data structure was changed to be allocated dynamically but
it wasn't being cleared leading to it 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.
