Hah, can you reproduce it? If so, can you detail how?
It's a typo.
WARN_ON(!cgroup_on_dfl(cp->css.cgroup) &&
nodes_equal(cp->mems_allowed, cp->effective_mems));
should be
WARN_ON(!cgroup_on_dfl(cp->css.cgroup) &&
!nodes_equal(cp->mems_allowed, cp->effective_mems));
Yes, it is. This warning disappeared after this patch.
