✨ queue_limits_cancel_update(9) ✨

Kernel API Manual — okay bestie, you're on the page for queue_limits_cancel_update(9), and honestly? It's a short one. A little cleanup queen of a function. Let's go 💅

---

🌸 NAME 🌸

queue_limits_cancel_update — cancel an atomic update of queue limits

No cap, that's the whole job description. She cancels. She updates nothing. She simply undoes.

---

🎀 SYNOPSIS 🎀

void queue_limits_cancel_update (struct request_queue *q );

POV: you call her with one pointer and she returns void, because she's not here to give you anything back — she's here to take the update away. Iconic behaviour tbh 🫶

---

🦋 ARGUMENTS 🦋

• q — queue to update. That's it. That's the whole argument list. She's low-maintenance like that ✨

---

💖 DESCRIPTION 💖

okay so here's the vibe: this function cancels an atomic update of the queue limits — the one that was started by queue_limits_start_update.

And when should you hit her up? when an error occurs after starting the update. That's literally her whole moment. Something went sideways mid-update? Bestie, call queue_limits_cancel_update and let her clean it up 🌸

fr fr, she exists for the error path. Don't leave your half-started atomic update hanging — that's not the vibe check you want to fail 😭
