You're missing the point, /dev/mem_notify would notify userspace of lowmem situations and allow it to respond appropriately in any number of ways before an oom condition exists. When the system (or cpuset, memory controller, etc) is oom, userspace can choose to defer to the oom killer so that it may kill a task that would most likely lead to future memory freeing with access to memory reserves. There is no additional oom killer limitation imposed here, nor can the oom killer kill a task hung in D state any better than userspace.
