I do not see how it would change the behavior. But maybe I wasn't clear enough. I just wanted to make all three: memcg->use_hierarchy = parent->use_hierarchy; memcg->oom_kill_disable = parent->oom_kill_disable; memcg->swappiness = mem_cgroup_swappiness(parent); in the same visual block so that we can split the function into three parts. Inherited values which don't depend on use_hierarchy, those that depend on use_hierarchy and the rest that depends on the previous decisions (kmem e.g.).
