__bfq_deactivate_entity(9)

📦 version 7.3.1, in nixpkgs unstable

✨ __bfq_deactivate_entity 💅

Okay so bestie, this one is from the Kernel API Manual, and it's a kernel-level function for the BFQ scheduler — deep lore, I know, but stay with me 🫶

🌸 NAME 🌸

__bfq_deactivate_entity — updates sched_data and the service trees for an entity, so the whole thing represents that entity as inactive ✨ Like, we're packing up its little desk and marking it "away" 🎀

🦋 SYNOPSIS 🦋

bool __bfq_deactivate_entity (struct bfq_entity *entity , bool
ins_into_idle_tree );

Yep, it returns a bool, takes a struct bfq_entity * and a bool, and no, we do not ask questions about the return value here — that's just how it is, periodt 💅

🌈 ARGUMENTS 🌈

  • entity — the entity being deactivated, aka the main character of this little operation 👑
  • ins_into_idle_tree — if this is false, the entity will not be put into the idle tree. That's it, that's the whole rule 😭

💖 DESCRIPTION 💖

If it's necessary and allowed, it puts entity into the idle tree. Cute, simple, conditional.

NOTE: entity may be on no tree at all if it's in service. Not a bug, just a vibe — don't come for me, that's literally what the manpage says 💀
