watchdog_stop(9)

okay so bestie, welcome to the watchdog_stop(9) page from the Kernel API Manual 💖 this is the stop-the-watchdog wrapper and we’re gonna get into the whole vibe: the argument, the lock situation, the 'nowayout' caveat, the return value, and every single SEE ALSO friend. no cap, all the facts are staying right here. 🫶

🌸 NAME 🌸

watchdog_stop — wrapper to stop the watchdog. periodt. 💅

✨ SYNOPSIS ✨

int watchdog_stop (struct watchdog_device *wdd );

🎀 ARGUMENTS 🎀

• wdd — the watchdog device to stop. that’s the one, bestie 🦋

💜 DESCRIPTION 💜

okay so here’s the tea: stop the watchdog if it is still active and unmark it active. ✨

If the 'nowayout' feature was set, the watchdog cannot be stopped — like, at all, bestie, no cap. 🚨

The caller must hold wd_data->lock. not optional, not a suggestion, that’s the rule. 🔒

⭐ RETURN ⭐

0 on success or a negative errno code for failure. so: slay on 0, sad little negative number on failure 😭
