batadv_set_l...ep_class_one(9)

💅 batadv_set_l...ep_class_one(9) — from the Kernel API Manual, bestie 🎀

okay so picture this: you're deep in the kernel, you've got a device, you've got queues, and somebody needs to tell lockdep which class each queue belongs to. that's it. that's the whole function. it's giving tiny-but-essential, and honestly? iconic. ✨

🌸 NAME 🌸

batadv_set_lockdep_class_one — set the lockdep class for a single tx queue, one queue at a time, no cap 🦋

---

🌈 SYNOPSIS 🌈

void batadv_set_lockdep_class_one (struct net_device *dev , struct netdev_queue *txq , void *_unused );

like, that's the whole signature. she's short, she's sweet, she returns void because she is not here to give you answers 💅

---

💖 ARGUMENTS 💖

• dev — the device that owns the tx queue. it's the main character here, the one whose queue we're about to touch. 👑
• txq — the actual tx queue to modify. this is the glow-up target, bestie. 🎀
• _unused — always NULL. literally always. it's there for the callback shape, it is not doing anything, and we respect that about it. 🙈

ngl bestie, if you got here from the _one variant, you probably want the non-_one batadv_set_lockdep_class(9) too — she's right there in the list above, go say hi 🫶
