STRUCT UBI_EBA_LEB_DESC(9)

💅 struct ubi_eba_leb_desc — EBA logical eraseblock descriptor 💅

okay so bestie, we're in the Kernel API Manual rn and this page is literally all about struct ubi_eba_leb_desc. it's short, it's sweet, it's giving "small but crucial supporting character" energy 🎀

---

✨ NAME ✨

struct ubi_eba_leb_desc — the EBA logical eraseblock descriptor, no cap 💖

---

🦋 SYNOPSIS 🦋

here's the whole struct, look at her:

struct ubi_eba_leb_desc {
    int lnum;
    int pnum;
 };

that's it. two little ints and she's done. iconic minimalism honestly 🫶

---

🌸 Members 🌸

• lnum — the logical eraseblock number. that's the LEB's logical identity, her government name if you will 💅
• pnum — the physical eraseblock where the LEB can actually be found. like, where she really lives 🏠✨

---

🔥 Description 🔥

so the whole reason this struct exists? it's here to hide EBA's internals from other parts of the UBI implementation. yes ma'am, encapsulation slay 💀✨ she's a privacy screen for the messy details, and honestly? we respect it.

and if you ever wanna know where a LEB is at, you just call ubi_eba_get_ldesc and she'll tell you the tea 🍵💖

ngl this is the kind of struct that looks like nothing but is lowkey holding the whole vibe together.
