batadv_choose_orig(9)

💅 batadv_choose_orig(9) — like, the Kernel API Manual edition 🎀

okay bestie, gather round, because this one is a tiny little function with main character energy and it lives in the Kernel API Manual. her whole job? she looks at a MAC address and tells you which bucket in the hash table it belongs in. that's it. that's the whole vibe. and honestly? iconic. ✨

---

🌸 NAME 🌸

batadv_choose_orig — returns the index of the orig entry in the hash table 🦋

---

✨ SYNOPSIS ✨

u32 batadv_choose_orig (const void *data , u32 size );

---

🎀 ARGUMENTS 🎀

• data — the MAC address of the originator node 🧚 (yes, it's a const void *, no she's not going to explain herself)
• size — the size of the hash table 💫

---

🔥 RETURN 🔥

the hash index where the object represented by data should be stored at. literally that's the whole point of her. slay. 👑

ngl bestie, don't sleep on this one — if you feed her the wrong size, the index she hands back is gonna be off and your whole hash table situation gets messy. she's not judging, she's just saying. 🙈

• batadv_hardif_neigh_put(9)
• batadv_neigh_node_put(9)

they're all linked in the same header, iykyk 💜

okay that's the whole page, bestie — written by the crew over in ./net/batman-adv, dated October 2026, and yes the footer really does just say batadv_choose_orig(9) again because she's consistent like that 💖🫶⭐
