If you fix the issue, kindly add following tag as appropriate

All warnings (new ones prefixed by >>):

kernel/cgroup/cpuset.c: In function 'update_prstate':

Oh, it was caused by a duplicated tmpmask in update_prstate() which isn't really necessary. Will send out a new version to fix that.

Thanks,
Longman
