Waiman Long 10dfcfda5c cgroup/cpuset: Fix violation of cpuset locking rule ...

[ Upstream commit 6ba34d3c73674e46d9e126e4f0cee79e5ef2481c ]

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")
