touch_softl...tchdog_sched(9)

💅 touch_softlockup_watchdog_sched(9) 💅

okay so bestie, welcome to the Kernel API Manual — this one's a tiny little function with main character energy, and honestly? she's doing a very specific job. let's get into it 🎀

✨ NAME ✨

touch_softlockup_watchdog_sched — touch watchdog on scheduler stalls 💖

like yes, that's literally the whole name, and yes, it's a mouthful, we been knew.

---

🌸 SYNOPSIS 🌸

notrace void touch_softlockup_watchdog_sched (void );

copy that exactly bestie, notrace and all — don't be out here retyping it from memory 😭

---

🦋 ARGUMENTS 🦋

• void — no arguments. that's it. that's the whole list. she takes nothing, she gives everything 🫶

---

⭐ DESCRIPTION ⭐

so here's the vibe: you call this bad boy when the scheduler may have stalled for legitimate reasons — reasons that are, like, totally valid and not a bug — and those stalls are preventing the watchdog task from executing. the example the page gives is the scheduler entering idle state 🧚

ngl this one's got a very strict guest list: this should only be used for scheduler events. that's not a suggestion, that's the rule 💅

for everything else, use touch_softlockup_watchdog. like, everything. all of it. don't make her do tasks she wasn't hired for 🙈
