schedule_tim...nterruptible(9)

💤 schedule_tim...nterruptible(9) — like, the Kernel API Manual one, bestie

okay so first thing, no cap: the page header literally reads schedule_tim...nterruptible(9) and that's from the Kernel API Manual, and yes it IS truncated mid-word and yes we're just gonna live with it 💅 the real function is schedule_timeout_uninterruptible and she's the main character here, periodt.

✨ NAME ✨

schedule_timeout_uninterruptible — sleep until timeout (uninterruptible) 🎀

Like, you go to sleep, and nobody can poke you awake. Iconic behaviour, lowkey terrifying, we'll get to that.

---

🌸 SYNOPSIS 🌸

signed long schedule_timeout_uninterruptible (signed long timeout );

That's the whole vibe. One argument in, a signed long back out. Slay.

---

🫶 ARGUMENTS 🫶

• timeout — the timeout value, and it's measured in jiffies ⏳ (yes, jiffies, the kernel's own little unit of time, don't ask me to convert it, that's a whole other manpage)

---

💖 DESCRIPTION 💖

So for the actual details you gotta go see schedule_timeout, fr fr — this page is like the ✨special edition✨ cover and schedule_timeout is the full novel. Go read that one for the lore.

The one thing this page absolutely needs you to know: task state is set to TASK_UNINTERRUPTIBLE before starting the timeout. 🔥

Which means — and I say this with love — your task is not interruptible while it's chilling in here. It's giving "do not disturb, I mean it." 💀
