STRUCT ISER_MEM_REG(9)

💅 struct iser_mem_reg(9) 💅

okay so bestie, welcome to the Kernel API Manual — yes, that Kernel API Manual — and today's main character is struct iser_mem_reg, which is literally just the iSER memory registration info. that's it, that's the vibe. it's giving "small struct, big responsibilities" ✨

---

🌸 NAME 🌸

struct iser_mem_reg — iSER memory registration info. no cap, that's the whole name and the whole job. 🫶

---

✨ SYNOPSIS ✨

struct iser_mem_reg {
    struct ib_sge sge;
    u32 rkey;
    struct iser_fr_desc *desc;
 };

like, look at her. three fields. effortless. 🎀

🦋 Members 🦋

• sge — the memory region sg element. literally the scatter-gather element for your memory region, doing its little thing 💫
• rkey — the memory region remote key, a u32. it's the key. remote. you know how it is 🔑
• desc — a pointer to the fast registration context, typed as struct iser_fr_desc *. pointer bestie pointing at her fr desc 💜

ngl bestie, that's the entire page — no hidden flags, no gotchas, no spicy caveats. sometimes a struct is just a struct and she's still iconic for it 💅💖
