batadv_hashdata_free_cb(9)

💅 batadv_hashdata_free_cb(9) — like, the hash element free callback, bestie

okay so real talk: this is a page straight out of the Kernel API Manual (that's the manual name, yes ma'am, batadv_hashdata_free_cb(9)), and it's honestly a tiny little icon. one function, four sections, no drama. let's get into it 🎀

---

✨ SYNOPSIS ✨

void batadv_hashdata_free_cb (struct hlist_node *node , void *arg );

that's it. that's the whole signature. void in, void out, no return value to obsess over. 🫶

---

🌸 ARGUMENTS 🌸

• node — the hlist node of the element that's being removed. like, the actual thing getting yeeted out of the hash. this is who you're freeing, no cap.
• arg — an opaque, caller-supplied argument that gets forwarded straight from the caller. "opaque" meaning don't peek inside, bestie, it's not your business — you just pass it along like a group-chat message. 🙈

---

💜 DESCRIPTION 💜

Release a previously inserted hash element.

and that's the whole vibe. something got put into the hash earlier, and now this callback is the one that sets it free. it's giving cleanup duty, it's giving main character energy at the end of the lifecycle. ✨

no cap: the entire description is literally that one sentence. i'm not adding lore that isn't there — that's the rule, and i respect the rule. 💅
