STRUCT FC4_PROV(9)

💖 struct fc4_prov(9) 💖

okay so this is a page from the Kernel API Manual — yes, the kernel docs, we're going there, and honestly? iconic of us. sit down bestie, this one's short and sweet 🍓

---

✨ NAME ✨

struct fc4_prov — FC-4 provider registration 🦋

like, it's the little struct that lets an FC-4 provider slide into the registry. that's the whole vibe check.

---

✨ SYNOPSIS ✨

struct fc4_prov {
    int (*prli)(struct fc_rport_priv *, u32 spp_len, const struct
fc_els_spp *spp_in, struct fc_els_spp *spp_out);
    void (*prlo)(struct fc_rport_priv *);
    void (*recv)(struct fc_lport *, struct fc_frame *);
    struct module *module;
 };

four members. four. that's it. it's giving minimalism, it's giving "i don't need 40 fields to serve cunt" 💅

---

✨ Members ✨

the squad 🫶

• prli — the handler for an incoming PRLI. yes bestie, PRLI. it gets called when one shows up and it's like "okay, i got this" 🔥
• prlo — the handler for session reset. things got messy, the session needs a reset, and this function is the one who handles it 😭
• recv — the handler for an incoming request. incoming request hits the door and this is who answers it 💀
• module — pointer to module. may be NULL. not required. it's optional. it's giving low-maintenance king energy 👑

ngl, <red>may be NULL</red> is a real caveat here — don't just assume module is always set, because it fr fr is not 🙈
