nand_write_oob(9)

💅 nand_write_oob(9) — a Kernel API Manual moment 💅

okay so bestie, grab your iced coffee because we are diving into the Kernel API Manual page for nand_write_oob(9) and honestly? it's giving main character energy. this is all about the [MTD Interface] and how NAND writes data and/or out-of-band info. no cap. 🎀

✨ NAME ✨

nand_write_oob — [MTD Interface] NAND write data and/or out-of-band

🌸 SYNOPSIS 🌸

int nand_write_oob (struct mtd_info *mtd , loff_t to , struct
       mtd_oob_ops *ops );

🎀 ARGUMENTS 🎀

• mtd — the MTD device structure. this is literally the whole device vibe, like the main character of the operation. you pass it in and it's like "say less, i got you." 👑
• to — the offset to write to. it's giving "where we dropping, bestie?" energy, lowkey. 📍
• ops — the oob operation description structure. this is the vibe check for the entire out-of-band situation, fr fr. it tells the function exactly what kind of magic we're making. 🦋

🔥 SEE ALSO 🔥

okay so this is the part where the man page absolutely goes feral with cross-references. no cap, there are like a million of them. but every single one matters so here we go:

that's literally the whole friend group, bestie. iykyk. 💜

aaaand that's the page! huge shoutout to the Kernel API Manual and nand_write_oob(9) living its best life in ./drivers/mtd/nand/raw. this beauty was last updated in October 2026, so it's giving vintage but still absolutely slaying. periodt. 💅✨
