At LSF we have discussed that we should keep a list of over-(soft)limit cgroups in a list which would be the first target for reclaiming (in round-robin fashion). If we are note able to reclaim enough from those (the list becomes empty) we should fallback to the all groups reclaim (what you did in this patchset). -- Michal Hocko SUSE Labs SUSE LINUX s.r.o.
