Memcg oom killer printing is controlled mostly by 
mem_cgroup_print_oom_info(), I don't see anything in the generic oom 
killer that should be removed and that I have not used even for memcg ooms 
in the past.

Perhaps there could be a case made for suppressing some of the 
hierarchical stats from being printed for memcg ooms and controlled by 
another memcg knob, but it doesn't sound vital.
