Hello, Linus.
* 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.
Thank you.
