fcoe_transport_lookup(9)

💅 fcoe_transport_lookup(9) — a Kernel API Manual moment

okay so bestie, welcome to fcoe_transport_lookup(9), straight out of the Kernel API Manual — yes it's giving "section 9, kernel internals, do not touch unless you know what you're doing" and honestly? iconic. 🎀

---

✨ NAME ✨

fcoe_transport_lookup — the little function that goes hunting for an fcoe transport that matches a netdev 🔍💖

🌸 SYNOPSIS 🌸

struct fcoe_transport * fcoe_transport_lookup (struct net_device *netdev
);

like literally that's the whole signature, no cap. it hands you back a struct fcoe_transport *. 🫶

🦋 ARGUMENTS 🦋

• netdev — the netdev you're looking for, and it's gonna be checked against, like, all the attached transports. it's the main character of this search ngl 👑

⭐ RETURN ⭐

a pointer to the fcoe transport that supports this netdev — slay, we found her 💅 — or NULL if it's not found 😭 (yes, NULL is a real possibility, check your return value fr fr).

🔥 DESCRIPTION 🔥

okay so the vibe here is short but load-bearing: the ft_mutex should be held when this is called.

bestie. hold the ft_mutex. this is not a suggestion-style moment, it's the documented requirement — don't be the one who calls this without it 🙈
