OK, I guess I remember something from the earlier memcg naturalization patch set discussions. This will still not help much for my case as the bigger memory pressure would cause reclaim also from the soft unlimited group which I would like to prevent. The other thing about soft limit only reclaim from the global reclaim is that currently all created memcgs are soft unlimited by default which might lead to unexpected results. Can we come up with a reasonable soft limit default? [...] -- Michal Hocko SUSE Labs SUSE LINUX s.r.o.
