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.

I've pulled it, but let me vent about this history a bit.
Look at commit c2a11971549b ("Merge branch 'for-5.13-fixes' into for-5.14").
Now tell me how that commit explains why it exists.
Merge commits need commit messages too.
In particular, they need commit messages that *explain* why they exist
in the first place, not just a one-liner that says what it does (and
does so badly at that).

for-5.13-fixes had comment updates across the file and I pulled them into
for-5.14 to avoid trivial context conflicts down the line. Yeah, I should
have commented on the rationale. Will add explanations from now on.
Thanks.
