A much better solution would be to lower the badness score that the oom

Anyway, oom killer shouldn't loop endlessly if it see TIF_MEMDIE on frozen
task,
it must go on and try to kill somebody else. We cannot wait for thawing this
task.
Did you read my suggestion? I quoted it above again for you. The badness
heuristic would only select those tasks to kill as a last resort in the
hopes they will eventually be thawed and may exit. Panicking the entire
machine for what could be isolated by a cgroup is insanity.
Maybe just fix this "panic" logic? OOM killer should panic only on global memory shortage.
