Subject: [PATCHSET] cpuset: drop cpuset->stack_list and ->parent, take#2
Date: Thu, 3 Jan 2013 13:44:03 -0800 [thread overview]
Message-ID: <1357249446-25075-1-git-send-email-tj@kernel.org> (raw)
Hello, guys.
This is the second take of "drop cpuset->stack_list and ->parent"
patchset. Other than being rebased on top of v3.8-rc2 + "cpuset:
decouple cpuset locking from cgroup core, take#2", nothing really has
changed.
The original patchset description follows.
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
v3.8-rc2 d1c3ed669a2d452cacfb48c2d171a1f364dae2ed
+ [1] "[PATCHSET cgroup/for-3.8] cpuset: decouple cpuset locking from cgroup core, take#2"
and available in the following git branch.
