Why cannot we simply provide a constructor for each page by the caller if there are special requirements? we currently have alt_map to do struct page allocation but nothing really prevents to make it more generic and control both allocation and initialization whatever suits a specific usecase. I really do not want make special cases here and there. -- Michal Hocko SUSE Labs
