__fc_linkdown(9)

💅 __fc_linkdown(9) — like, the Kernel API Manual page, bestie

okay so before we even start: this is from the Kernel API Manual, section 9, and the star of the show is __fc_linkdown. she's a handler. she handles transport linkdown events. no cap. let's get into it 🫶

✨ NAME ✨

__fc_linkdown — the handler for transport linkdown events 💀

like literally, when a transport link goes down, this is the function that gets called to deal with it. main character energy fr fr.

---

🌸 SYNOPSIS 🌸

void __fc_linkdown (struct fc_lport *lport );

that's it. that's the whole signature. void return, one argument. clean, minimal, iconic. ✨

---

🎀 ARGUMENTS 🎀

• lport — the lport whose link is down 😭 like. the actual local port object that's having a moment right now because its link is down. that's the one you pass in.
