💅 throtl_peek_queued(9) 💅

okay bestie so you're in the Kernel API Manual and the page you opened is throtl_peek_queued — yes, that's the one, section 9, we're deep in kernel land and honestly? it's giving backstage-pass energy 🎟️✨

🌸 NAME 🌸

throtl_peek_queued — peek the first bio on a qnode list 👀

like, just a lil peek. not a grab. we're window-shopping the bio list, not buying 🛍️

---

✨ SYNOPSIS ✨

struct bio * throtl_peek_queued (struct list_head *queued );

that's the whole signature, character for character, no cap. struct bio * comes back out, struct list_head *queued goes in, and the space before the closing paren is exactly like that. do not come for me, that's how it's written 🫶

---

🎀 ARGUMENTS 🎀

• queued — the qnode list to peek at 👀 it's the list you're being nosy about, that's it, that's the whole parameter

---

🦋 DESCRIPTION 🦋

okay so here's the vibe check on how this thing behaves:

always take a bio from the head of the iops queue first. always. head of the line, first in the door, main character of the queue 🔥

and if that queue is empty? then we take it from the bps queue instead — because the whole overall idea is fetching bios from the head, and we're keeping that energy no matter which queue we end up pulling from 💖

so: iops head first, bps head as the fallback, and the "fetch from the head" philosophy stays intact the whole time. slay 💅
