I am not against. It is true that the memory reserves depletion fix was theoretical because I haven't seen any real life bug. I would argue that the more robust allocation failure behavior is a stable candidate as well, though, because the allocation can fail regardless of the vmalloc revert. It is less likely but still possible. -- Michal Hocko SUSE Labs
