💅 devfreq_monitor(9) — the Kernel API Manual glow-up

okay bestie, welcome to devfreq_monitor(9), straight out of the Kernel API Manual ✨ this one is short and sweet but she's important, so pay attention 🫶

---

✨ NAME ✨

devfreq_monitor — the girl who periodically polls devfreq objects ⏰💖 like she's checking her phone every five seconds but make it kernel infrastructure, no cap.

---

🌸 SYNOPSIS 🌸

void devfreq_monitor (struct work_struct *work );

literally one line, one function, one vibe 💅 copy it exactly, don't be cute with the spacing.

---

🎀 ARGUMENTS 🎀

• work — the work struct that's used to run devfreq_monitor periodically. that's it, that's the whole argument 🫶 she's the little scheduling handle that keeps the polling loop going, main character energy fr fr.
