   - What happens when a new cgroup created ?

 mem_cgroup_create() is called =)
 Heh, jokes apart, I don't really follow here. What exactly do you mean?
 There shouldn't be anything extremely out of the ordinary.

Sorry, too short words.

Assume a cgroup with
	cgroup.memory.limit_in_bytes=1G
	cgroup.memory.kmem.limit_in_bytes=400M

When a child cgroup is created, what should be the default values.
'unlimited' as current implementation ?
Hmm..maybe yes.

I think so, yes. I see no reason to come up with any default values
in memcg. Yes, your allocations can fail due to your parent limits.
But since I never heard of any machine with
9223372036854775807 bytes of memory, that is true even for the root memcg =)
