📦 version 7.3.1, in nixpkgs unstable

✨ svc_pool_wake_idle_thread 💤➡️🔥

okay so bestie, this is a page from the Kernel API Manual, section 9 — yes, the big-girl kernel section, we love that for us. It's called svc_pool_wake_idle_thread, and it's literally just "hey sleepyhead, wake up" but for service threads. no cap. 🫶

💖 NAME 💖

svc_pool_wake_idle_thread — awaken an idle thread in @pool 🌸

like, that's the whole gig. it finds a thread that's been napping and gently (read: atomically) tells it to get up. ✨

🎀 SYNOPSIS 🎀

void svc_pool_wake_idle_thread (struct svc_pool *pool );

that signature is giving "small function, big responsibility", honestly. 💅

🦋 ARGUMENTS 🦋

  • pool — the service thread pool 👑 this is the pool we're waking somebody up inside, so like, know which pool you're dealing with, bestie.

🌸 DESCRIPTION 🌸

So here's the vibe: this thing can be called from soft IRQ or from process context. Either one. It's flexible like that. 😌

What it does is find an idle service thread and mark it as BUSY — and the way it does that is atomic with respect to other calls to svc_pool_wake_idle_thread. So like, no two callers are gonna grab the same sleepy thread and double-book it. the race condition could never, fr fr. 🔥

ngl this atomicity bit is the whole personality of this function — if you're calling it from multiple contexts, that's the detail you care about. 💀

💜 SEE ALSO 💜

like, that's a whole friend group right there. go read them too, iykyk. 🍓
