Agreed. The biggest issue in cpuset is if hotplug makes a cpuset's cpulist empty the tasks in it will be moved to an ancestor cgroup, which requires holding cgroup lock. We have to either change cpuset's behavior or eliminate the global lock.
Does that have to happen synchronously? Can't we have a cgroup operation which asynchronously pushes all tasks in a cgroup to its parent from a work item? Thanks. -- tejun
