Hi Tetsuo
> Since origin_memcg_name is printed for both memcg OOM and !memcg OOM, it is strange that origin_memcg_name is updated only when memcg != NULL. Have you really tested !memcg OOM case?
if memcg == NULL , origin_memcg_name will also be NULL, so the length
of it is 0. origin_memcg_name will be "(null)". I've tested !memcg OOM
case with CONFIG_MEMCG and !CONFIG_MEMCG, and found nothing wrong.
Thanks
