cgroup, the past, present and future

Project: Linux kernel

Control cgroup has evolved organically, too organically, leading to various fundamental and practical issues in both the kernel and its consumers in the userland. cgroup has recently been going through a lot of changes to get the situation under control. The effort is two-pronged - the kernel cgroup itself is being restructured and updated extensively and a central agent overseeing the whole cgroup configuration is being implemented in userland. This presentation examines what went wrong in the past, how we're trying to correct those now, and what future may bring for cgroup.
