ibmvmc_release_crq_queue(9)

💅 ibmvmc_release_crq_queue — Release CRQ Queue

Okay bestie, so this one lives in the Kernel API Manual (section 9, kernel API girlies rise 🎀), and it's literally the cleanup queen of the ibmvmc world — it releases the CRQ Queue. That's it, that's the vibe. ✨

---

✨ SYNOPSIS ✨

void ibmvmc_release_crq_queue (struct crq_server_adapter *adapter );

Notice the void — it's giving "I do the work, I don't come back with receipts." 💅

---

🌸 ARGUMENTS 🌸

• adapter — a crq_server_adapter struct, aka the whole little world this function is tidying up. You hand it over, it handles the release. 🫶

---

⭐ RETURN ⭐

• 0 — Success, slay, we ate, no cap 👑
• Non-Zero — Failure 😭 (something went sideways)
