✨ NAME ✨

vdo_waitq_init — literally just initializes a vdo_wait_queue. That's the whole gig. No cap. 🎀

---

✨ SYNOPSIS ✨

void vdo_waitq_init (struct vdo_wait_queue *waitq );

ok so it returns void, meaning it gives you nothing back, and it takes exactly one pointer. That's it. That's the signature. Iconic behavior honestly. 🌸

• vdo_waiter_is_waiting(9) — the vibe check for a single waiter ✨
• vdo_waitq_has_waiters(9) — does the queue have waiters? finds out 🔥
• vdo_waitq_num_waiters(9) — how many waiters? counts them 👑
