__ap_flush_queue(9)

💅 __ap_flush_queue(9) — like, the kernel API manual page, bestie

okay so real talk: this is a page straight out of the Kernel API Manual (section 9, the kernel-functions girlies), and it's about one very specific little function. it's short, it's sweet, it does one thing, and honestly? it ate. let's get into it 🫶

---

✨ NAME ✨

__ap_flush_queue — the request-flusher. that's it, that's the whole vibe. it flushes requests 💅

---

🌸 SYNOPSIS 🌸

void __ap_flush_queue (struct ap_queue *aq );

no return value, babe — it's a void. it just does the thing and leaves. main character energy honestly.

---

🎀 ARGUMENTS 🎀

• aq — a pointer to the AP queue. that's your queue, bestie. hand it over and it's getting flushed 🌊

---

🦋 DESCRIPTION 🦋

so what it does is: it flushes all the requests from the request/pending queue of an AP device. literally all of them. the request queue and the pending queue, emptied out. no crumbs left. ✨

no cap, that's the entire description — this manpage is a short one and we respect her for it.

lowkey obsessed with how a function that wipes an entire queue gets two whole sentences. iconic minimalism. 👑
