batadv_choose_claim(9)

💖 batadv_choose_claim(9) — like, the Kernel API Manual page you didn't know you needed 💖

okay so bestie, picture this: it's a Kernel API Manual page (yes, that's the manual name, she's fancy), and it's all about one tiny little function that does one tiny little job. and honestly? she ate. 🎀

---

✨ NAME ✨

batadv_choose_claim — literally just picks the right bucket for a claim. that's the whole gig. iconic behaviour, no notes. 💅

---

🌸 SYNOPSIS 🌸

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

look at her go. two args, one u32 out. clean, minimal, main character energy. ✨

---

🦋 ARGUMENTS 🦋

• data — the data to hash. yeah, that's it, that's the whole vibe. 🫶
• size — size of the hash table. she needs to know how big the bucket collection is before she starts picking, iykyk.

---

🔥 RETURN 🔥

the hash index of the claim. one number. that's your answer. slay. 👑

💜 SEE ALSO 💜

bestie reminder: every single one of those is a real cross-reference from the original page, i did not make any of them up. copy them exactly if you're typing them out. 💀

anyway, that's the page! source location is ./net/batman-adv, dated October 2026, and if you need to cite her properly it's batadv_choose_claim(9). mwah. 💋
