STRUCT NAND_BBT(9)

💅 NAME 💅

struct nand_bbt — the bad block table object ✨

okay so first things first, bestie: this is a page out of the Kernel API Manual, and it's all about struct nand_bbt(9). That's the bad block table object, periodt. That's literally the whole name, no cap 🫶

---

🎀 SYNOPSIS 🎀

so the struct looks like this and honestly it's giving minimalist icon energy:

struct nand_bbt {
    unsigned long *cache;
 };

one member. one. that's it. she's lowkey unbothered 💅

---

🌸 Members 🌸

• cache — the in-memory BBT cache 💖 (yes that's the entire description, the manpage is not gonna elaborate, and honestly? respect the brevity)

ngl bestie, Members is the whole of the documentation here — one field, one line. the way that a struct can be this chill 😭

---

🦋 SEE ALSO 🦋

the kernel file these live in is ./include/linux/mtd/nand.h, and it's surrounded by an absolutely iconic friend group — like genuinely 49 of them, go off 👑
