Agreed. This came up recently when another lowmem killer was proposed and
the suggestion was to enable the memory controller to be able to have the
memory threshold notifications with eventfd(2) and cgroup.event_control.
It would be very nice to have a generic lowmem notifier (like
/dev/mem_notify that has been reworked several times in the past) rather
than tying it to a particular cgroup, especially when that cgroup incurs a
substantial overhead for embedded users.
