Hello, guys.
cpuset implements its own descendant iteration using cpuset->stack_list and has its own ->parent pointer. There's nothing cpuset specific about descendant walking or finding the parent. This patchset makes cpuset use cgroup generic API instead.
0001-cpuset-implement-cgroup_rightmost_descendant.patch 0002-cpuset-replace-cpuset-stack_list-with-cpuset_for_eac.patch 0003-cpuset-remove-cpuset-parent.patch
0001 implements cgroup_rightmost_descendant() which can be used to skip subtree during pre-order tree walk. Michal, maybe memcg can use it too?
0002 replaces cpuset->stack_list with generic for_each_descendasnt_pre().
0003 replaces cpuset->parent with cgroup->parent.
This patchset is on top of
cgroup/for-3.8 fddfb02ad0 ("cgroup: move list add after list head initilization") + [1] "[PATCHSET cgroup/for-3.8] cpuset: decouple cpuset locking from cgroup core"
and available in the following git branch.
