Tejun Heo ebda41dd17 cgroup: Fix css_task_iter_advance_css_set() cset skip condition ... commit c596687a00 upstream. While adding handling for dying task group leaders c03cd7738a ("cgroup: Include dying leaders with live threads in PROCS iterations") added an inverted cset skip condition to css_task_iter_advance_css_set(). It should skip cset if it's completely empty but was incorrectly testing for the inverse condition for the dying_tasks list. Fix it.
