Hello, Linus.
* Christian extended clone3 so that processes can be spawned into cgroups
directly. This is not only neat in terms of semantics but also avoids grabbing
the global cgroup_threadgroup_rwsem for migration.
* Daniel added !root xattr support to cgroupfs. Userland already uses xattrs on
cgroupfs for bookkeeping. This will allow delegated cgroups to support such
usages.
* Prateek tried to make cpuset hotplug handling synchronous but that led to
possible deadlock scenarios. Reverted.
* Other minor changes including release_agent_path handling cleanup.
Thanks.
