For me, `PlainRead.java` is failing on a pure cgroups v2 system (passes on v1):


;$JT_HOME/bin/jtreg -jdk:build/linux-x86_64-normal-server-release/jdk test/hotspot/jtreg/containers/cgroup/PlainRead.java
Test results: failed: 1


(I noticed this in a downstream backport and traced it back up here)

I've put my JTreport here: https://jmtd.net/tmp/jdk11u_8230305_PlainRead_jtreport/JTreport/html/index.html
