tipc_link_failover_prepare(9)

💖 tipc_link_failover_prepare(9) — a Kernel API Manual moment 🎀

okay so bestie, welcome to the Kernel API Manual entry for tipc_link_failover_prepare(9), and trust me when I say this one is a little backstage-pass function — it's the special-edition version of something else and it literally tells you so. let's get into it ✨

---

✨ NAME ✨

tipc_link_failover_prepare — the function that preps tnl for link failover 🦋

🌸 SYNOPSIS 🌸

void tipc_link_failover_prepare (struct tipc_link *l , struct tipc_link
*tnl , struct sk_buff_head *xmitq );

like, yes, it returns void — no little gift back, it just does the thing 💅

👑 ARGUMENTS 👑

• l — the failover link. this is the link, the main character of the failover storyline 🫶
• tnl — the tunnel link. its supporting role, but make no mistake, it's essential 😌
• xmitq — the queue for messages to be xmited. everything waiting to go out lives here, no cap 📬

🔥 DESCRIPTION 🔥

so here's the vibe: this is a special version of the precursor tipc_link_tnl_prepare. it's giving "same energy, different edition" 💫

and if you want the full lore — the whole why and how — go check out tipc_node_link_failover for details, because that's where the story actually gets told 🧚

ngl bestie, this page is short on purpose. the function itself is a helper, and the real explanation lives over in tipc_node_link_failover. don't come for me, come for the cross-reference 💀
