My question was marked as a duplicate, and sincerely, I don't get it. Please explain it to me.

My question: Best practice: mitigating OOM kills of KVM VMs [duplicate]
The other: Using linux oom_score_adj to aim the oom daemon at the right target

So, in my question I ask "What can I do to do ABC", while the other asks "How do I use instrument XYZ".

I see that usage of instrument XYZ is an answer and achieves goal ABC. But the two questions aren't the same.

So the other question together with its answer would be a valuable answer to my question, since I didn't know about oom_score_adj.

So, I really don't understand it and I would really appreciate somebody explaining this to me. If I can't ask such questions here, where else could I go? Especially since such questions are out of scope for SO and SU.
