Merge branch 'for-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup updates from Tejun Heo:
- cgroup.kill is added which implements atomic killing of the whole
subtree.
Down the line, this should be able to replace the multiple userland
implementations of "keep killing till empty".
- PSI can now be turned off at boot time to avoid overhead for
configurations which don't care about PSI.
