> I made a memory namespace earlier to contain some processes, and it's not showing up in sudo lsns, What kernel do you run? I have never heard about memory namespaces. And http://man7.org/linux/man-pages/man7/namespaces.7.html http://man7.org/linux/man-pages/man7/namespaces.7.html neither. Did you possibly mean memory cgroups? Obviously lsns doesn't show them. I don't know a tool that gives a good overview over cgroups at one glance. I have used custom scripts based on find /sys/fs/cgroup/ -name tasks in the past.
