onenand_unlock_all(9)

💅 onenand_unlock_all(9) — the "free the blocks" page

Okay bestie, so this one's straight out of the Kernel API Manual, and the whole entire point of onenand_unlock_all(9) is in the NAME section below. It's a tiny function, no cap — but it's a load-bearing tiny function, so let's give it the respect it deserves. 🫶

✨ NAME ✨

onenand_unlock_all — the OneNAND Interface function that unlocks all the blocks. Yes, all of them. Every last one. 💅

---

🌸 SYNOPSIS 🌸

void onenand_unlock_all (struct mtd_info *mtd );

That's it. That's the whole signature. Iconic, honestly. It returns void, so there's no error code to obsess over — it just goes and does the thing. 🎀

---

🦋 ARGUMENTS 🦋

• mtd — the MTD device structure. This is your MTD device vibe check right here — hand it over and it knows which device we're talking about. 🧚

---

⭐ DESCRIPTION ⭐

Unlock all blocks.

Literally that. That's the description. The kernel devs said "we're not gonna over-explain this one" and honestly? Respect. 🔥

So: you give it the MTD device structure, it goes and unlocks every single block on the thing. No partial vibes, no "just this one block" energy — all of them. Main character behavior only. 👑

Okay real talk bestie, this one's short on purpose — short page, zero drama, just "unlock all blocks" and a truly massive friend list. Go read the others if you want lore. 🍓
