Maybe no HUNK with -next and -mm.... -Kame == memcg: remove -EINTR at rmdir() By commit "memcg: move charges to root cgroup if use_hierarchy=0", no memory reclaiming will occur at removing memory cgroup. So, we don't need to take care of user interrupt by signal. This patch removes it. (*) If -EINTR is returned here, cgroup will show WARNING.
