This doesn't seem like a good idea unless the application supports the
"Node 0" prefix in /proc/meminfo.
Of course, /cgroup/memory/..../memory.meminfo , a new file, will use the same
format of /proc/meminfo. Above is just an example of bind-mount.
If any application really cares about the amount of memory available to
it, it should be taught to be memcg aware. Then do something like
Considering the container as a kind of virtualization, Some kind of
transparent way is required.
