Others show yet different behaviors. Applied to cgroup/for-3.7-hierarchy w/ acks added. git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup.git for-3.7-hierarchy The branch is based on top of the current mainline (fbcbe2b3c 3.6-rc5) and only contains hierarchy related changes. The branch will be kept stable unless I do something completely stupid, so please feel free to pull into other trees as necessary. Thanks. -- tejun
