fc_host_fpin_rcv(9)

💅 fc_host_fpin_rcv ✨ Kernel API Manual 🦋

okay so bestie, welcome to the fc_host_fpin_rcv page 💖 this one's short and sweet and it lives in the Kernel API Manual, and honestly? it's giving "small function, big responsibility" energy 👑

---

🎀 NAME 🎀

fc_host_fpin_rcv — the routine that processes a received FPIN 💫 (no cap, that's literally the whole job)

---

🌸 SYNOPSIS 🌸

void fc_host_fpin_rcv (struct Scsi_Host *shost , u32 fpin_len , char
*fpin_buf , u8 event_acknowledge );

she takes four things, she returns void, she minds her own business 🫶

---

✨ ARGUMENTS ✨

• shost — the host that the FPIN was received on 🖥️ like, which host, bestie, we need to know
• fpin_len — length of the FPIN payload, in bytes 📏 measured in bytes, not vibes
• fpin_buf — pointer to the FPIN payload 🎯 the actual goods
• event_acknowledge — 1, if LLDD handles this event 🙈 ok so set her to 1 when the LLDD is the one handling this event, periodt

---

🧚 NOTES 🧚

This routine assumes no locks are held on entry 🔒😌 like, walk in with your hands empty, bestie — no locks held, that's the whole vibe check.

fr fr, that's a real assumption, not a suggestion — no locks are held on entry when you call this 💀
