fc_lport_ns_resp(9)

💅 fc_lport_ns_resp(9) — the Kernel API Manual, bestie edition ✨

Okay so welcome to the Kernel API Manual page for fc_lport_ns_resp(9), and no, we are not skipping anything, we are reading the whole thing together 🫶

✨ NAME ✨

fc_lport_ns_resp — literally the function that handles the response to a name server registration exchange 🌸

✨ SYNOPSIS ✨

void fc_lport_ns_resp (struct fc_seq *sp , struct fc_frame *fp , void
*lp_arg );

That's the whole signature, copy it exactly, do not touch it, it's giving iconic 💅

✨ ARGUMENTS ✨

• sp — the current sequence in the exchange 🌀
• fp — the response frame 📦
• lp_arg — the Fibre Channel host port instance, aka your lport bestie 👑

✨ DESCRIPTION ✨

So here's the thing you actually need to know:

Locking Note: this function gets called without the lport lock held 😭 — but then it locks, calls an _enter_* function or fc_lport_error, and then unlocks the lport. So it's a lock-call-unlock situation, fr fr. Don't forget the unlock, that's the whole vibe check 🔥
