I mean... sacrifice child is a whole new one to me! Clearly whoever programmed that in knew what they were doing.
Yeah lol I'm familiar with "kill child" in a process management context, but I've never seen the word "sacrifice" come up. Is that a thing?
/*
- If any of p's children has a different mm and is eligible for kill,
- the one with the highest oom_badness() score is sacrificed for its
- parent. This attempts to lose the minimal amount of work done while
- still freeing memory. */
Nice. Imagine the lady in the post's face when she learns that "oom badness" is how they decide which child to sacrifice.
What's that from?
From the source file oom_kill.c in the linux kernel. But it seems this has been reworded or changed since 2019. That's the commit that removed this.
It sounds funny but it's not an uncommon phrase.
