Document kernel versions affected by cgroup and squashfs filesystems
Description
It is evident that the interaction of cgroups memory limits and the squashfs filesystem implementations on older, but still in use, linux kernel versions. This has been noted in several issues and investigated in a write up posted in the HPCng slack:
- https://github.com/apptainer/singularity/issues/5850
- https://github.com/apptainer/singularity/issues/5800
- https://hpcng.slack.com/files/U47TWTU1L/F02ERQ8S0AZ/singularity-squashfs-oom-issue.pdf
We should generate documentation articulating the issue and listing kernel versions known to be problematic as a part of cgroups.rst
page.
Once documentation is generated, we should include a comment on the related issues with the affected range to make the information easy to find.
