hwspin_lock_unregister(9)

📦 version 7.3.1, in nixpkgs unstable

💅 hwspin_lock_unregister(9) — the kernel API manual, but make it cute 🎀

okay bestie, so this is a page from the Kernel API Manual (section 9, iykyk) and it's literally all about ✨hwspin_lock_unregister✨ — yes the name is a mouthful, we cope 💜

🌸 NAME 🌸

hwspin_lock_unregister — unregister an hw spinlock device 🦋

so like... it takes an hw spinlock device and goes "okay you're done here, bye" 💅

✨ SYNOPSIS ✨

int hwspin_lock_unregister (struct hwspinlock_device *bank );

that's the whole vibe. one function, one arg, one int coming back at you 🫶

🎀 ARGUMENTS 🎀

  • bank — the hwspinlock device, which usually provides numerous hw locks 👑 like, not just one lock, a whole little squad of them. it's giving "main character with an entourage" fr fr

🦋 DESCRIPTION 🦋

so here's the tea ☕ — this function should be called from the underlying platform-specific implementation, to unregister an existing (and unused) hwspinlock. not new, not in-use — existing and unused. read that twice, bestie, it's important 🔥

and it should be called from a process context (might sleep) — so like, don't you dare call it from some spicy atomic context, because it might sleep 😭 that's a whole thing. process context only. periodt.

⚠️ also, ngl, "platform-specific implementation" is doing a lot of work in that sentence — that's literally the layer that's supposed to be calling this, not just anybody 🙈

⭐ RETURN ⭐

  • 0 on success ✨ (slay)
  • or an appropriate error code on failure 💀 (not slay, but at least you know)

like, the whole friend group 💖 first up, this lives in the kernel file ./drivers/hwspinlock/hwspinlock_core.c, and then there's the extended crew:

that's all of them, no cap, I didn't skip a single one 🫶

and that's the page, bestie!! 🎀 this iconic little manual entry lives in ./drivers/hwspinlock and it's dated October 2026 — so yeah, future vibes ⭐🌙 go forth and unregister responsibly 💜✨
