cpuset code stopped using cgroup_lock in favor of cpuset_mutex long ago.

* get_online_cpus(), which is called from the static_branch update,

* can't be called inside the cgroup_lock. cpusets are the ones
|

* enforcing this dependency, so if they ever change, we might as well.
|
|
||||||
*
|
|
||||||
* schedule_work() will guarantee this happens. Be careful if you need
|
|
||||||
* to move this code around, and make sure it is outside
|
|
||||||
* the cgroup_lock.
