onenand_unlock(9)

💅 onenand_unlock(9) — the Kernel API Manual, but make it make sense

okay so bestie, welcome to the Kernel API Manual entry for onenand_unlock — yes it's a (9) page, yes that means it's a kernel-internal function, and yes we are gonna read it together like the little group-chat study session that we are. 🫶

✨ NAME ✨

onenand_unlock — [MTD Interface] unlock block(s). that's it, that's the whole vibe. it unlocks blocks. blocks get unlocked. slay. 🔓

---

🎀 SYNOPSIS 🎀

int onenand_unlock (struct mtd_info *mtd , loff_t ofs , uint64_t len );

like, it takes three things and gives you back an int, no cap. ✨

---

🌸 ARGUMENTS 🌸

• mtd — the MTD device structure. it's the device, she's the main character, everybody else is just visiting. 👑
• ofs — offset relative to the start of the mtd. so like, where in the device we're starting. 📍
• len — number of bytes to unlock. how much we're unlocking, measured in bytes, fr fr. 📏

---

🦋 DESCRIPTION 🦋

unlock one or more blocks.

that's literally it. that's the description. it's giving "minimalist icon" and honestly we respect it. you point at some bytes, you say how many, and the block(s) get unlocked. periodt. ✅
