ENUM NAND_ECC_ALGO(9)

💅 enum nand_ecc_algo(9) — like, the NAND ECC algorithm enum, bestie

okay so this is from the Kernel API Manual and it's genuinely one of those little pages that's short but iconic — it's the enum that tells you which error-correcting algorithm a NAND device is using. NAND flash is messy (bits flip, it's a whole thing 😭) so ECC is the main character here. Let's get into it 🫶

✨ SYNOPSIS ✨

enum nand_ecc_algo {
    NAND_ECC_ALGO_UNKNOWN ,
    NAND_ECC_ALGO_HAMMING ,
    NAND_ECC_ALGO_BCH ,
    NAND_ECC_ALGO_RS

};

that's it. that's the whole enum. four constants, no cap. 💅

🎀 Constants 🎀

• NAND_ECC_ALGO_UNKNOWN — literally the "no idea bestie" option. Unknown algorithm 🙈
• NAND_ECC_ALGO_HAMMING — the Hamming algorithm. classic, vintage, still serving ✨
• NAND_ECC_ALGO_BCH — the Bose-Chaudhuri-Hocquenghem algorithm. yes that's really the name, and yes it ate 👑
• NAND_ECC_ALGO_RS — the Reed-Solomon algorithm. also a full-name baddie, also slay 🌸

like I said — a lot of besties. go read them all, iykyk 💜

ngl there are no options, no exit statuses, no env vars on this page — it's just the enum and its constants, so don't go looking for plot twists that aren't there 💀

okay that's the whole page, mwah 🎀 sourced from ./include/linux/mtd, dated October 2026, and it's the enum nand_ecc_algo(9) page — go forth and correct those bits, bestie ✨🦋💖
