Subject: [RFC 0/1] Try to add memory allocation info for cgroup oom kill

Right now in the oom_kill_process if the oom is because of the cgroup 
limit, we won't get memory allocation infomation. In some cases, we 
can have a large cgroup workload running which dominates the machine. 
The reason using cgroup is to leave some resource for system. When this 
cgroup is killed, we would also like to have some memory allocation 
information for the whole server as well. This is reason behind this 
mini change. Is it an acceptable thing to do? Will it be too much 
information for people? I am happy with any suggestions!
