💅 batadv_frag_merge_packets(9) 💅

okay bestie, welcome to the Kernel API Manual ✨ this one's a whole function page and honestly? it's iconic. it lives in the kernel, it deals with fragments, and it's about to make your whole chain situation make sense 🫶

🌸 NAME 🌸

batadv_frag_merge_packets — merge a chain of fragments 💖

like, literally take a chain of fragments and merge them. that's the vibe. that's the whole job. no cap.

✨ SYNOPSIS ✨

struct sk_buff * batadv_frag_merge_packets (struct hlist_head *chain );

she returns a struct sk_buff *, she takes one argument, she's booked and busy 💅

🎀 ARGUMENTS 🎀

  • chain — head of chain with fragments 🌈 this is the pointer to the struct hlist_head that sits at the front of your little fragment friend group. she's the main character of the list, everybody else follows her.

🦋 DESCRIPTION 🦋

okay so here's the tea ☕:

Expand the first skb in the chain and copy the content of the remaining skb's into the expanded one. that's it. that's the whole glow-up — first one gets bigger, the rest get absorbed into her. it's giving merger. it's giving "you're coming with me" energy 💀

and after doing so, clear the chain. periodt. the chain gets emptied out, no leftovers, no crumbs, we don't do clutter here 🧹✨

fr fr though — first skb expands, the others get copied in, then the chain is cleared. those three things, in that order, that's the whole personality of this function 🎀

👑 RETURN 👑

the merged skb or NULL on error 🫶

so like, either you get your beautiful merged sk_buff *, or you get NULL and you have to deal with it. no in-between, she's not ambiguous 💅

🔥 SEE ALSO 🔥

Kernel file ./net/batman-adv/fragmentation.c — go read her, she's the source of truth 📖💖

and then the whole friend group:

ngl that's a stacked lineup 😭 every single one of them, exactly as listed, no skips, no edits, iykyk 🌟

and that's the page bestie!! 💜 from ./net/batman-adv, dated October 2026, signed off on batadv_frag_merge_packets(9) — stay fragmented, stay fabulous, slay 🦋✨🎀
