Creates a helper function to return non-zero if a task is a member of a memory controller: int task_in_mem_cgroup(const struct task_struct *task, const struct mem_cgroup *mem); When the OOM killer is constrained by the memory controller, the exclusion of tasks that are not a member of that controller was previously misplaced and appeared in the badness scoring function. It should be excluded during the tasklist scan in select_bad_process() instead.
