Subject: Backport d583d360a6 into 5.12 stable
Date: Tue, 22 Jun 2021 18:30:46 +0200	[thread overview]
Message-ID: <11282373.oIR2C0Pl9h@spock> (raw)

Hello.

I'd like to nominate d583d360a6 ("psi: Fix psi state corruption when 
schedule() races with cgroup move") for 5.12 stable tree.

Recently, I've hit this:

```
kernel: psi: inconsistent task state! task=2667:clementine cpu=21 psi_flags=0 
clear=1 set=0
```

and after that PSI IO went crazy high. That seems to match the symptoms 
described in the commit message.

Thanks.
