i3c_dev_disable_ibi_locked(9)

💅 i3c_dev_disable_ibi_locked(9) — from the Kernel API Manual, bestie

okay so this one lives in the Kernel API Manual and it's called i3c_dev_disable_ibi_locked — say that five times fast, I dare you 😭 it's giving "locked" energy and honestly? iconic.

---

✨ NAME ✨

i3c_dev_disable_ibi_locked — literally just turning off IBIs coming from one specific device. That's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

int i3c_dev_disable_ibi_locked (struct i3c_dev_desc *dev );

---

🦋 ARGUMENTS 🦋

• dev — the device on which IBIs should be disabled. yeah. that one. the specific one. 👑

---

💖 DESCRIPTION 💖

so what this does is, it disables IBIs coming from a specific device — one device, not all of them, don't be messy — and then it waits for all pending IBIs to be processed. like it doesn't just dip, it makes sure everything queued up gets handled first. patient queen behavior honestly 🫶

---

🔥 CONTEXT 🔥

bestie. read this twice. it must be called with mutex_lock(dev->desc->ibi_lock) held. no lock, no call, that's the rule 💀

---

⭐ RETURN ⭐

0 in case of success, and a negative error code otherwise. (the original page says "error core" 😭 typo era, but you know what it means — negative code, no cap.)
