fc_seq_lookup_recip(9)

💅 fc_seq_lookup_recip — a vibe check on the Kernel API Manual ✨

Okay so bestie, we're in the <pink>Kernel API Manual</pink> today and the main character is literally fc_seq_lookup_recip. Periodt. Let's get into it 🎀

---

🌸 NAME 🌸

fc_seq_lookup_recip — find a sequence where the other end originated the sequence 🫶

Like, you're not the one who started it, they did, and now you gotta go find that sequence. No cap.

---

✨ SYNOPSIS ✨

enum fc_pf_rjt_reason fc_seq_lookup_recip (struct fc_lport *lport ,
struct fc_exch_mgr *mp , struct fc_frame *fp );

Look at her. Iconic signature. Ate. 👑

---

💖 ARGUMENTS 💖

• lport — the local port that the frame was sent to 🏠 like, this is the address it landed at bestie
• mp — the Exchange Manager you're looking the exchange up from 🔍 that's the whole point, we're doing a lookup here
• fp — the frame that's attached to the sequence we're hunting for 🦋 the actual thing we're trying to match up

---

🦋 DESCRIPTION 🦋

So here's the tea ☕ — if fc_pf_rjt_reason comes back as FC_RJT_NONE, then this function will have a hold on the ep, and it's lowkey on the caller to release it. 🫶

Like, not me handing you the ep and expecting you to clean up after yourself, but yes, exactly that. The hold is yours now. Release it. Please and thank you 💅✨

Fr fr, don't forget the release — it's giving "leave it on read" energy and nobody wants that 😭
