✨ rvt_driver_mr_init(9) ✨

okay so this is a page from the Kernel API Manual bestie, and it's about one very specific little function. let's get into it 🫶

---

🌸 NAME 🌸

rvt_driver_mr_init — literally just "init MR resources per driver", that's the whole vibe 💅

---

🦋 SYNOPSIS 🦋

int rvt_driver_mr_init (struct rvt_dev_info *rdi );

---

🎀 ARGUMENTS 🎀

• rdi — the rvt dev struct. that's it, that's the one thing you hand it ✨

---

💖 DESCRIPTION 💖

so what does it actually do? it does any initialization needed when a driver registers with rdmavt. that's the whole job. no cap, that's the description 💀

like yes it's short, but it's giving "small function, big responsibility" energy 👑

---

⭐ RETURN ⭐

• 0 on success 🎉
• errno on failure 😭
