The LRU's will be shared, my vision is
LRU

Mem-----+ +----Mem
That two or more mem_cgroup's can refer to the same LRU list and have
their own resource counters. This setup will be used in the case
of a hierarchy, so that a child can share memory with its parent
and have it's own limit.
The mem_cgroup will basically then only contain a reference
to the LRU list.
