Re: [PATCH v3 3/9] cgroup/cpuset: Fix violation of cpuset locking rule

The cpuset fields that manage partition root state do not strictly follow the cpuset locking rule that update to cpuset has to be done with both the callback_lock and cpuset_mutex held. This is now fixed by making sure that the locking rule is upheld.

Fixes: 3881b86128d0 ("cpuset: Add an error state to cpuset.sched.partition") Fixes: 4b842da276a8 ("cpuset: Make CPU hotplug work with partition) Signed-off-by: Waiman Long longman@redhat.com

Applied to cgroup/for-5.15.

Thanks.
