watchdog_get_timeleft(9)

okay bestie, we're in the Kernel API Manual and this page is all about watchdog_get_timeleft(9) ✨

🌸 NAME 🌸

watchdog_get_timeleft — a lil wrapper that tells you how much time is left before the watchdog straight-up reboots your system 💅

✨ SYNOPSIS ✨

Here's the vibe check on the function signature — keep it exactly like this:

void watchdog_get_timeleft (struct watchdog_device *wdd , unsigned int
       *timeleft );

🎀 ARGUMENTS 🎀

• wdd — this is the watchdog device struct you're pulling the remaining time from, like the main character of this whole operation 👑
• timeleft — this is where the time that's left gets stored, literally the countdown vibe ⏳

💖 DESCRIPTION 💖

okay so this function gets the time before a watchdog will reboot (if not pinged). Pretty straightforward, right? But here's the tea: the caller must hold wd_data->lock — like, don't even think about calling this without the lock, no cap, fr fr 💀
