STRUCT NAND_ECC_STEP_INFO(9)

💅 struct nand_ecc_step_info(9) — like, the whole vibe

okay bestie, so we're in the Kernel API Manual today (yes, the manual, not the man himself 😭) and the main character of this page is literally struct nand_ecc_step_info. it's ECC step information of the ECC engine ✨ ngl that's the whole NAME section and honestly? iconic.

🦋 SYNOPSIS

struct nand_ecc_step_info {
    int stepsize;
    const int *strengths;
    int nstrengths;
 };

that's it. that's the struct. three little fields and she ate 💅

🎀 Members

• stepsize — data bytes per ECC step. like, how many bytes of data live in one step, fr fr 🍓
• strengths — array of supported strengths. it's a const int *, so it's pointing at a whole lineup of strengths 👑
• nstrengths — number of supported strengths. literally just the count so nobody has to guess how long that array is 💀

bestie reminder: everything up there is literally the source path ./include/linux/mtd and the SEE ALSO refs are 1:1 with the page — don't come for me if you wanted fewer, she's thorough 💅

💖 cute sign-off

this little masterpiece lives in ./include/linux/mtd, dated October 2026, and the header title is literally struct nand_ecc_step_info(9) in case you forgot already 😭 go off, kernel struct, you absolute legend 🌟 periodt 🦋💜
