mpi3mr_alloc...q_q_segments(9)

💅 NAME 💅

mpi3mr_alloc_op_req_q_segments — bestie, this one allocs you a segmented req pool ✨

So this is a page from the Kernel API Manual — very demure, very kernel, very (9). Let's get into it 🎀

---

🌸 SYNOPSIS 🌸

int mpi3mr_alloc_op_req_q_segments(struct mpi3mr_ioc *mrioc, u16 qidx);

---

🦋 ARGUMENTS 🦋

• mrioc — the adapter instance reference, like, your actual controller's whole deal 🫶
• qidx — the request queue index, i.e. which queue we're talking about, babe 💅

---

✨ DESCRIPTION ✨

Okay so the vibe here is simple and iconic: this function allocates segmented memory pools for the operational request queue. That's it. That's the whole personality. It's giving "setup era" — you call it before the req queue can actually do req-queue things 🔥

---

⭐ RETURN ⭐

• 0 on success 🎉
• non-zero on failure 😭 (so like, always check it, fr fr)
