cpufreq_unregister_notifier(9)

okay bestie, welcome to the Kernel API Manual page for cpufreq_unregister_notifier(9) — it’s giving “small function, very important cleanup era” ✨🧚

✨ NAME ✨

cpufreq_unregister_notifier — Unregister a notifier from cpufreq. periodt. 💅

🌸 SYNOPSIS 🌸

int cpufreq_unregister_notifier (struct notifier_block *nb , unsigned int list );

🎀 ARGUMENTS 🎀

• nb — the notifier block to be unregistered, bestie. that’s the little guy leaving the list.
• list — CPUFREQ_TRANSITION_NOTIFIER or CPUFREQ_POLICY_NOTIFIER. those are the list options, no cap.

💅 DESCRIPTION 💅

okay so this one removes a notifier from one of the cpufreq notifier lists. literally its whole job. 💖 highkey the simplest unregister arc.

🚨 heads up: this function may sleep — yes, fr fr — and it has the same return values as blocking_notifier_chain_unregister. so that’s the return-value vibe check, iykyk. 😭
