✨ rnbd_rerun_if_needed(9) ✨

okay so this is a page from the Kernel API Manual bestie, like the actual kernel docs, and we're about to make it make sense 💅

---

🎀 NAME 🎀

rnbd_rerun_if_needed — rerun next queue marked as stopped

🌸 SYNOPSIS 🌸

bool rnbd_rerun_if_needed (struct rnbd_clt_session *sess );

🦋 ARGUMENTS 🦋

• sess — the session you wanna rerun a queue on. that's it, that's the whole vibe 🫶

💖 DESCRIPTION 💖

okay so picture this: every single CPU has its own little list of HW queues, right? and those queues are the ones that should be rerun. so this function goes and finds that list with the HW queues, grabs the list lock 🔒, picks up the first HW queue out of the list, and requeues it. slay. that's literally the whole thing.

lowkey the way it works is: find list → take list lock → take first HW queue → requeue it. iconic behavior honestly ✨

⭐ RETURN ⭐

true if the queue was actually requeued, false otherwise. no cap, that's the whole return story 💀

🧚 CONTEXT 🧚

does not matter. literally does not matter at all. call it from wherever, the context is not the moment 🙈✨
