But any semantic exported to the userspace and real application depending on it is carved in stone for ever. And this is the case here I am afraid. So if we really need some sort of soft unmapping or reparenting a memory from a memcg then we really need to find a different way. I do not see a straightforward way right now TBH. -- Michal Hocko SUSE Labs
