STRUCT UBI_EBA_TABLE(9)

💅 struct ubi_eba_table(9) — a Kernel API Manual moment

okay so bestie, we're deep in the kernel API manual today (yes, that manual), and the star of the show is struct ubi_eba_table. it's giving low-level, it's giving internal, and honestly? iconic.

---

✨ NAME ✨

struct ubi_eba_table — literally the LEB → PEB association info 🎀 like that's the whole job.

---

🦋 SYNOPSIS 🦋

struct ubi_eba_table {
    struct ubi_eba_entry *entries;
 };

that's it. that's the struct. short, sweet, and absolutely not for you to poke at (more on that in a sec 👀).

---

🌸 Members 🌸

• entries — the LEB to PEB mapping, and it's one entry per LEB fr fr. every LEB gets its lil entry, no skipping, no favorites. 🫶

---

💖 Description 💖

so listen. this structure is private to the EBA logic and should be kept here — like, right here, where it lives. do not move it, do not pass go, do not collect $200. 🙈

it's the thing encoding the LEB to PEB association table, and heads up: it is subject to changes. so if you were thinking about building your whole personality around this struct's layout… don't. 💀 it can and will shift on you. no cap.

bestie warning: private + subject to changes = hands off unless you're literally the EBA logic. this is not a "let me just reach in and grab it" situation. 😭
