batadv_exit(9)

💅 batadv_exit(9) — the Kernel API Manual page, bestie edition

okay so you're looking at batadv_exit(9) from the Kernel API Manual, and honestly? she's the goodbye-girl of the batman-adv module. short page, big job. let's get into it 🎀

---

✨ NAME ✨

batadv_exit — the batman-adv module exit function. yes, THE exit function. the one who closes the door when the party's over. 🚪💫

---

✨ SYNOPSIS ✨

void batadv_exit (void );

that's it. that's the whole signature. no cap. 🫶

---

✨ ARGUMENTS ✨

• void — no arguments. literally zero. she takes nothing, she gives everything. 💅

---

✨ DESCRIPTION ✨

okay so what does she actually do? two things, and both matter:

• Unregister the netdevice notifier — she takes that notifier off the list, no more callbacks, we're done here 📴
• Tear down all global state allocated by batadv_init — everything batadv_init set up, she dismantles. the full cleanup. the anti-batadv_init. 🔥

ngl bestie, this is teardown code — she's undoing global state, so this is not the vibe to be calling randomly mid-operation 🙈
