mpi3mr_free...q_q_segments(9)

🎀 mpi3mr_free_op_req_q_segments(9) 🎀

okay bestie, welcome to the Kernel API Manual ✨ — yes, that's the whole manual name, we're fancy here. This lil page is all about one function, and honestly? It's giving cleanup crew energy. Let's get into it 💅

---

🌸 NAME 🌸

mpi3mr_free_op_req_q_segments — frees request memory segments 🧹

Like, it literally hands the memory back. No cap.

---

✨ SYNOPSIS ✨

void mpi3mr_free_op_req_q_segments (struct mpi3mr_ioc *mrioc , u16 q_idx );

That's the whole signature, keep it exactly like that, void return and all 🫶

---

💖 ARGUMENTS 💖

• mrioc — the adapter instance reference. Think of it as the main character of this whole operation 👑 it's your struct mpi3mr_ioc * and it knows everything about the controller.
• q_idx — the operational request queue index, typed as u16. It's literally which queue you're talking about, bestie 🔢

---

🦋 DESCRIPTION 🦋

So here's the vibe: this function frees the memory segments that were allocated for the operational request queue 🌈

That's it. That's the whole job. It's the undoing of the alloc, the "okay we're done here" moment, the graceful exit 🚪✨

---

🍓 RETURN 🍓

Nothing. 💀

Not 0, not -ENOMEM, not a status code — it's a void function, so there's literally nothing coming back. It's giving "I did the thing, no notes" 🙈

and that's the whole page!! 💜 one function, two arguments, zero return values, and a truly iconic amount of cross-references 🌟

this lil masterpiece lives at ./drivers/scsi/mpi3mr, dated October 2026, and it's filed under mpi3mr_free...q_q_segments(9) — slay, go free those segments bestie 💅✨🦋
