cgroup_attach_task() calls subsys->attach_task() after cgroup_task_migrate(); however, cgroup_attach_proc() calls it before migration. This actually affects some of the users. Update cgroup_attach_proc() such that ->attach_task() is called after migration.
There have been a patch posted recently:
"[PATCH][BUGFIX] cgroups: fix ordering of calls in cgroup_attach_proc"
that not only fixes that ordering but also only attach the task if the
migration happened correctly (task not exited).
Can somebody queue it for 3.2 ?
