Like, literally. It tells you how much time is left on a timer. That's the whole vibe. No cap. 🫶

✨ SYNOPSIS ✨

ktime_t __hrtimer_get_remaining (const struct hrtimer *timer , bool
adjust );

that's it, that's the whole signature 💅 writes out as a ktime_t, takes a const struct hrtimer *timer and a bool adjust — iconic, concise, no notes 🔥

---

✨ ARGUMENTS ✨

• timer — the timer to read 🌸 like, hand me the timer and I'll tell you what's in it, bestie
• adjust — adjust relative timers when CONFIG_TIME_LOW_RES=y ⚙️ lowkey important: this only does its little adjustment thing when that config is set, so don't come for her if nothing moves on your build 🧚
