nand_default_block_markbad(9)

💅 nand_default_block_markbad(9) — from the Kernel API Manual, bestie

okay so real talk: this is a page straight out of the Kernel API Manual, and the star of the show is nand_default_block_markbad. Buckle up, it's a short one but it ate 💅

---

✨ NAME ✨

nand_default_block_markbad — [DEFAULT] mark a block bad via bad block marker 🎀

---

🌸 SYNOPSIS 🌸

int nand_default_block_markbad (struct nand_chip *chip , loff_t ofs );

---

🦋 ARGUMENTS 🦋

• chip — the NAND chip object, like, the whole vibe of the chip itself 💖
• ofs — the offset from the start of the device. yes bestie, from the device start, not wherever you feel like it 🎯

---

👑 DESCRIPTION 👑

so this is the default implementation, and that's literally the whole point — a hardware specific driver can override it whenever it wants to do its own thing ✨ It's the one that handles all the details for writing a bad block marker to a block. no cap, that's the job 🫶

ok so that's the whole page 💀 it's short but it's iconic, y'know? default implementation, overridable, marker gets written, done. periodt 💅
