clk_notifier_register(9)

🌸 NAME 🌸

okay so this is clk_notifier_register(9) from the Kernel API Manual, and bestie, it's literally the page for clk_notifier_register — register a clock rate-change notifier callback 💅✨

---

✨ SYNOPSIS ✨

int clk_notifier_register (struct clk *clk , struct notifier_block *nb
);

---

🎀 ARGUMENTS 🎀

• clk — clock whose rate we are interested in 🕰️
• nb — notifier block with callback function pointer 📞

---

💅 DESCRIPTION 💅

okay so real talk, bestie — this is the part where the page gives you the actual pro tip 👑

ProTip: debugging across notifier chains can be frustrating. Make sure that your notifier callback function prints a nice big warning in case of failure.

no cap, that's the whole mood: notifier chains can be lowkey frustrating to debug, so make your callback print a nice big warning if something fails. your future self will thank you 🫶😭
