💅 nanddev_bbt_...block_status(9)

okay so bestie, we're in the Kernel API Manual today and this page is literally about asking a NAND device "hey girl, what's the status of this eraseblock?" 🦋 It's the BBT version of a vibe check, no cap.

✨ NAME ✨

nanddev_bbt_get_block_status — returns the status of an eraseblock 🌸

🎀 SYNOPSIS 🎀

int nanddev_bbt_get_block_status (const struct nand_device *nand ,
unsigned int entry );

💖 ARGUMENTS 💖

• nand — the nand device, your main character of the hour 👑
• entry — the BBT entry you're curious about, like the exact address in the group chat you're scrolling to 🙈

🔥 RETURN 🔥

It hands you back a positive number — a nand_bbt_block_status status, iconic behavior 💅 — or -ERANGE if entry is bigger than the BBT size. so if you're out here indexing past the end, the kernel is literally gonna tell you "girl, no" and throw -ERANGE at you 😭 periodt.

k so -ERANGE here means your entry is bigger than the BBT size. that's the whole warning. don't go past the end, bestie, it's not cute 🙈
