scx_rescue_end(9)

📦 version 7.3.1, in nixpkgs unstable

💅 scx_rescue_end(9) — like, the Kernel API Manual page you actually wanna read 🎀

okay so bestie, welcome to scx_rescue_end(9) from the Kernel API Manual — yes that Kernel API Manual — and no cap, this one's short but it's packed. it's giving "small function, big consequences." let's get into it 🦋

✨ NAME ✨

scx_rescue_end — end the rescue execution on @rq 💫

like, literally the function that says "okay the rescue sesh is OVER, everybody out" 🫶

🌸 SYNOPSIS 🌸

void scx_rescue_end (struct rq *rq );

that's it. that's the whole vibe check. one arg, returns nothing, main character energy 🔥

🎀 ARGUMENTS 🎀

  • rq — rq of interest 👀 like, the runqueue you're curious about. that's the one. that's your girl.

💖 DESCRIPTION 💖

okay so here's the tea ☕ — when no rescuee is left pending, the session is over, and the balance above one quantum dies with it. literally dies. gone. 💀

and like, that's a good thing actually, because otherwise that balance would become a banked license to preempt the cid owner long after the starvation ended — and ngl bestie, that is not the vibe. we are NOT letting stale preemption privileges hang around post-starvation. that's giving messy. 🙈

but!! ✨ while waiters remain ✨, the accrued deficit belongs to the queue and carries into the next rescue. so it's not lost, it's just, like, relocating. lowkey iconic behavior honestly 👑

fr fr the rule is simple: session over → the above-one-quantum balance goes with it; waiters still waiting → the deficit stays with the queue and rolls on into the next rescue. two different fates, both on purpose 💅
