💅 fc_linkdown(9) — from the Kernel API Manual, bestie 💅

okay so real talk, this is fc_linkdown, a section-9 kernel function, and she's the one who handles transport linkdown events. like, when the link goes down? she's on it. main character energy fr fr 💖

like, the whole libfc friend group showed up for her. we love a supportive network stack 🧚💜

ngl bestie, if you're here it's probably because lport's link went bye-bye and you need to know what runs. that's the whole assignment. slay. 🦋

and that's the page! brought to you by ./drivers/scsi/libfc — October 2026 — mwah, ily, go read your kernel logs 💅✨
