STRUCT UBI_SGL(9)

✨ struct ubi_sgl(9) ✨

okay bestie, this one's from the Kernel API Manual, and it's literally the glow-up wrapper your scatter list has been waiting for 💅

---

🌸 NAME 🌸

struct ubi_sgl — the UBI scatter gather list data structure, and yes she has a whole personality 🎀

---

🦋 SYNOPSIS 🦋

struct ubi_sgl {
    int list_pos;
    int page_pos;
    struct scatterlist sg[UBI_MAX_SG_COUNT];
 };

like, that's the whole vibe. three members. no notes. 👑

---

💖 Members 💖

• list_pos — your current position in sg[] 📍 think of it as the little "you are here" dot on the mall map
• page_pos — your current position in sg[list_pos] 🎯 yeah, it's a whole second layer of "where am I", she contains multitudes
• sg — the scatter gather list itself, the main character, the actual goods 🌟

---

🌈 Description 🌈

so ubi_sgl is a cute little wrapper around a scatter list, and what it does is keep track of where you are — both the current position in the list (list_pos) and the current list item (page_pos) 🫶

and the reason it does that? so it can be used across multiple ubi_leb_read_sg calls ✨ like, it remembers where it left off between calls so you don't have to. it's giving personal assistant energy, honestly. no cap. 💀
