hwspin_unlock_raw(9)

💖 hwspin_unlock_raw — the Kernel API Manual, bestie edition 💖

okay so this is the manpage for hwspin_unlock_raw from the Kernel API Manual, and honestly? it's giving "short but iconic." let's get into it 🎀

---

✨ NAME ✨

hwspin_unlock_raw — unlock hwspinlock 🔓✨

like, that's the whole job. she unlocks. she's done. periodt.

---

🌸 SYNOPSIS 🌸

void hwspin_unlock_raw (struct hwspinlock *hwlock );

no cap, that's the entire call. you hand her the lock, she lets it go 🫶

---

🦋 ARGUMENTS 🦋

• hwlock — a previously-acquired hwspinlock which we want to unlock. lowkey the main character of this whole situation 💅 you literally cannot do this without her.

---

⭐ DESCRIPTION ⭐

okay so real talk: this function will unlock a specific hwspinlock. that's it, that's the vibe check, she ate 🔥

but here's the part where you gotta listen, bestie, because this is the important bit 👑 — hwlock must be already locked (e.g. by hwspin_trylock) before calling this function. and I mean it fr fr: it is a bug to call unlock on a hwlock that is already unlocked 😭💀

⚠️ so don't be out here unlocking things that aren't locked. that's not a vibe. that's a bug. no cap.
