# Cgroup v2简介

从Linux 4.5内核开始cgroup v2接口已经被标记为官方发布，意味着不再使用devel标签并且可以作为新型cgroup2 fs类型来挂载。有关 Cgroup v2接口的更改，参考 [cgroup v2](https://events.linuxfoundation.org/sites/events/files/slides/2014-KLF.pdf)这个slide。

在YouTube上有一个[NYLUG Presents: Tejun Heo on cgroups and cgroups v2 (Feb 18th, 2015) ](https://www.youtube.com/watch?v=PzpG40WiEfM)视频，是Cgroup V2开发者Tejun Heo的演讲。(10:45)
