fc_lport_scr_resp(9)

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

okay so this is a page straight outta the Kernel API Manual, section 9, and it's all about handling the response to a State Change Register (SCR) request. FC girlies rise 🦋

---

✨ NAME ✨

fc_lport_scr_resp — handle the response to a State Change Register (SCR) request. that's it, that's the whole vibe 🎀

---

🌸 SYNOPSIS 🌸

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

---

🫶 ARGUMENTS 🫶

• sp — the current sequence in the SCR exchange. lowkey the thread of the convo 🧵
• fp — the response frame. the actual reply that came back, iconic ✨
• lp_arg — the Fibre Channel lport port instance that sent the registration request. yes, the main character 👑

---

🔥 DESCRIPTION 🔥

Locking Note: this function gets called without the lport lock held — but no cap, it will lock, then call an _enter_* function or fc_lport_error, and then unlock the lport. so it's a whole lock → do the thing → unlock situation and it handles all of that for you 💅

fr fr, read the locking note again. called unlocked, does its own locking, cleans up after itself. periodt.
