schedule_timeout_idle(9)

💤 NAME

schedule_timeout_idle — sleep until timeout (idle) 😴

okay so this is the schedule_timeout_idle(9) page from the Kernel API Manual, and its whole thing is literally sleep until timeout (idle) — cute, simple, iconic 💅.

✨ SYNOPSIS ✨

signed long schedule_timeout_idle (signed long timeout );

🎀 ARGUMENTS 🎀

• timeout — the timeout value in jiffies ⏳

🦋 DESCRIPTION 🦋

okay bestie, for the full deets you gotta see schedule_timeout — this page says “See schedule_timeout for details” and we are not gonna pretend otherwise 🫶.

Before starting the timeout, the task state is set to TASK_IDLE 🧊. It’s similar to schedule_timeout_uninterruptible, except this task will not contribute to load average. That’s the whole vibe: similar energy to schedule_timeout_uninterruptible, but zero load-average contribution, periodt 💅.
