💅 write_bbt(9) — the Kernel API Manual, but make it cute 💅

---

🌸 SYNOPSIS 🌸

int write_bbt (struct nand_chip *this , uint8_t *buf , struct
nand_bbt_descr *td , struct nand_bbt_descr *md , int chipsel );

it's giving "one function, five arguments, main character energy" 💅

---

🎀 ARGUMENTS 🎀

• this — the NAND chip object, aka the star of the show 👑
• buf — a temporary buffer, just vibing in the background, doing its little job 🦋
• td — the descriptor for the bad block table, iconic, essential, we stan 🎀
• md — the descriptor for the bad block table mirror, because one table is never enough, slay ✨
• chipsel — selector for a specific chip, and it's -1 for all of them, periodt 💀
