STRUCT NAND_ECC_PROPS(9)

💅 struct nand_ecc_props(9) 💅

okay so bestie, welcome to the Kernel API Manual — yes that's the manual name, we're fancy now 🎀 — and today's main character is struct nand_ecc_props, aka the little struct that holds all your NAND ECC properties. she's giving config-glamour, no cap ✨

---

🌸 NAME 🌸

struct nand_ecc_props — NAND ECC properties, literally the vibe check for your error correction 💖

---

🦋 SYNOPSIS 🦋

here's the whole glow-up, copy it exactly bestie, don't touch a single character:

struct nand_ecc_props {
    enum nand_ecc_engine_type engine_type;
    enum nand_ecc_placement placement;
    enum nand_ecc_algo algo;
    unsigned int strength;
    unsigned int step_size;
    unsigned int flags;
 };

look at her. six fields. absolutely iconic 👑

---

✨ Members ✨

okay so let's meet the cast, one by one 🫶

• engine_type — the ECC engine type, like which engine is driving this whole thing 🚗
• placement — the OOB placement (if relevant, so don't come for me if it's not) 📍
• algo — the ECC algorithm (if relevant — again, conditional, iykyk) 🧮
• strength — the ECC strength. how strong. 💪
• step_size — number of bytes per step, so you know how big each step is 👟
• flags — misc properties, the little extras, the garnish of the struct 🌿

ok that's the whole page bestie, nothing skipped, every last reference accounted for — read it, love it, man it 💅

and finally, the cute sign-off: this lil beauty lives in ./include/linux/mtd, dated October 2026, and yes the page title is still struct nand_ecc_props(9) because she's the main character, periodt 🌈💖
