clocksource_touch_watchdog(9)

💅 clocksource_touch_watchdog(9) — from the Kernel API Manual, bestie 🎀

okay so real talk, this one is a tiny little page from the Kernel API Manual and it's honestly giving "small but mighty" ✨ so let's get into it 💖

---

🌸 NAME 🌸

clocksource_touch_watchdog — literally just updates the watchdog, that's the whole gig 🫶

---

✨ SYNOPSIS ✨

void clocksource_touch_watchdog (void );

like… it takes nothing and returns nothing, no cap 💀

---

🦋 ARGUMENTS 🦋

• void — no arguments. zero. nada. the void is voiding 🙈

---

💜 DESCRIPTION 💜

okay so here's the vibe: you call this bad boy to update the watchdog after exception contexts such as kgdb, so the watchdog doesn't incorrectly trip 😭 like, we are NOT letting it trip by accident, that's not the energy we're bringing today 💅

⚠️ heads up bestie: this might fail when the kernel was stopped in code which holds watchdog_lock. so like… it's a whole thing, don't come for me, that's just how it is 🙈
