vhost_vq_get_backend(9)

💅 vhost_vq_get_backend(9) — the Kernel API Manual, bestie edition 💅

okay so you're in the vhost_vq_get_backend(9) page of the Kernel API Manual, and honestly? this one's a little snack. tiny function, one job, zero drama. let's get into it 🎀

---

✨ NAME ✨

vhost_vq_get_backend — get backend.

that's it. that's the whole name section. she is concise and honestly we respect it 👑

---

🌸 SYNOPSIS 🌸

void * vhost_vq_get_backend (struct vhost_virtqueue *vq );

like, look at her. returns a void *, takes a pointer to a struct vhost_virtqueue named vq, and that's the entire vibe check. no cap 🫶

---

🦋 ARGUMENTS 🦋

• vq — the manpage literally says -- undescribed -- 💀💀 the docs said "not me explaining this one" and clocked out. so yeah, vq is here, vq is a thing, and the official documentation has left the chat on this one. iconic of them tbh 😭

---

💖 DESCRIPTION 💖

• vq — Virtqueue.

that's the description. one line. the original prose is out here doing the absolute bare minimum and honestly? main character energy is knowing when to stop typing 💅✨

so like, plainly: this is the getter for the virtqueue's backend private data. vq is the virtqueue. go off, tiny manpage 🌈

---

🔥 CONTEXT 🔥

⚠️ bestie, read this one twice: you need to call this with vq->mutex acquired. the lock. hold it. don't be out here raw-dogging a virtqueue without the mutex, that's not the move 🙈

---

👑 RETURN 👑

returns the private data that was previously set with vhost_vq_set_backend. so it's literally the "what did we stash in here earlier" function. getter/setter duo, they're a matching set, we stan a consistent API 🍓

---

⭐ SEE ALSO ⭐

• Kernel file ./drivers/vhost/vhost.h — go read the header, the lore lives there 📖
• vhost_vq_set_backend(9) — the other half of the duo, the setter to this getter, they come as a pair fr fr 💜

---

and that's the whole page, bestie!! short, sweet, mutex-locked. this gem comes to you from ./drivers/vhost, dated October 2026 — so like, future-dated docs, we love a timestamp that's ahead of schedule 🧚✨ slay, bye!! 🌸💅
