cgroup: reorganize css_task_iter
This patch reorganizes css_task_iter so that adding effective css support is easier. * s/->cset_link/->cset_pos/ and s/->task/->task_pos/ for consistency * ->origin_css is used to determine whether the iteration reached the last css_set. Replace it with explicit ->cset_head so that css_advance_task_iter() doesn't have to know the termination condition directly. * css_task_iter_next() currently assumes that it's walking list of cgrp_cset_link and reaches into the current cset through the current link to determine the termination conditions for task walking. As this won't always be true for effective css walking, add ->tasks_head and ->mg_tasks_head and use them to control task walking so that css_task_iter_next() doesn't have to know how css_sets are being walked. This patch doesn't make any behavior changes. The iteration logic stays unchanged after the patch. Signed-off-by: Tejun Heo <tj@kernel.org> Acked-by: Li Zefan <lizefan@huawei.com>
