💅 nanddev_bbt_init(9) 💅

okay so bestie, welcome to the nanddev_bbt_init page — yeah it's a kernel API manual situation, and honestly? this one's a little cutie. it does exactly one thing and it does it slayfully. let's get into it 🎀

---

✨ NAME ✨

nanddev_bbt_init — Initialize the BBT (Bad Block Table)

like, the whole vibe of this function is "wake the BBT up." that's it. that's the post. 🌸

---

🦋 SYNOPSIS 🦋

int nanddev_bbt_init (struct nand_device *nand );

one function, one argument, returns an int. lowkey elegant, ngl 💅

---

🍓 ARGUMENTS 🍓

• nand — the NAND device. your main character struct. this is who you're initializing the BBT for, so like… don't forget to pass it, bestie 😭

---

💖 DESCRIPTION 💖

Initialize the in-memory BBT.

that's it!! that's the whole description!! it's giving "short and confident." the BBT lives in memory, and this function is the one that sets it up. no cap, sometimes the simplest functions are the most iconic 👑

---

🌈 RETURN 🌈

• 0 — success!! we ate, no crumbs, everything worked 🎉
• a negative error code — otherwise. so if you see a negative number coming back, that's your sign something went sideways 🙈

---

🧚 SEE ALSO 🧚

• Kernel file ./drivers/mtd/nand/bbt.c — the home base for all this BBT lore, iykyk
• nanddev_bbt_cleanup(9)
• nanddev_bbt_update(9)
• nanddev_bbt_get_block_status(9)
• nanddev_bbt_set_block_status(9)

like the whole friend group fr fr — init, cleanup, update, get, set. go read them all, they're all part of the same era 💜

---

heads up bestie: init without a matching cleanup is a situationship you do NOT want. nanddev_bbt_cleanup(9) exists for a reason 🫶

okay that's the page!! mwah 💋 this little love letter to the kernel was brought to you by ./drivers/mtd/nand, dated October 2026 — remember us fondly, and go initialize some bad block tables responsibly ✨🎀🦋
