Hello Jens,
This is v3 of the patch series.
Changes since v2:
* added acks from Tejun
* fixed some typos pointed out by Tejun
* fixed condition checking for too long think time in patch 1/5
Changes since v1:
* added missing export of cgroup_is_descendant()
If you find the series too hasty for the current merge window, just postpone it
for the next one.
