fcoe_hostlist_lookup(9)

✨ NAME ✨

okay so bestie, welcome to fcoe_hostlist_lookup(9) from the Kernel API Manual — the icon whose whole job is finding the local port associated with a given net device. lowkey simple, highkey important. 🎀

🫶 SYNOPSIS 🫶

struct fc_lport * fcoe_hostlist_lookup (const struct net_device *netdev );

🌸 ARGUMENTS 🌸

• netdev — the netdevice used as a key. that's the key right there, no substitutions, periodt. 🔑

💅 DESCRIPTION 💅

Locking: Must be called with the RTNL mutex held. like, fr fr, this is the whole note: you gotta have the RTNL mutex held when you call it. the vibe check is locking, bestie. 😭

🌈 RETURN 🌈

NULL or the local port. that's the answer — either NULL or the local port, and that's it. 💖
