This already exists: applications can receive memory pressure events (such as the system reaching "medium" level, where you may want to start freeing some caches) via /sys/fs/cgroup/memory/.../memory.pressure_level. See https://www.kernel.org/doc/Documentation/cgroup-v1/memory.tx....

The first two nota benes explicitly describe this document being outdated and not what most people expect when it comes to “memory controller”. I am not certain that citing this is a great example.
