In addition, Tejun made offlined css iterable and split css_tryget() and css_tryget_online(), which would allow memcg to pin the css until the last charge is gone while continuing to iterate and reclaim it on hierarchical pressure, even after it was offlined.
One more question. With reparenting enabled, the number of cgroups (lruvecs) that must be iterated on global reclaim is bound by the number of live containers, while w/o reparenting it's practically unbound, isn't it? Won't it be the source of latency spikes?
