erase_aeb(9)

💅 erase_aeb(9) — bestie edition ✨

okay so real talk, this is erase_aeb(9) from the Kernel API Manual, and it's genuinely one of those little functions that keeps the whole UBI wear-leveling situation from spiraling. let me walk you through it 🫶

---

🌸 NAME 🌸

erase_aeb — literally erases a PEB that got handed to you via UBI attach info PEB. that's the whole vibe. 🎀

---

✨ SYNOPSIS ✨

int erase_aeb (struct ubi_device *ubi , struct ubi_ainf_peb *aeb , bool
sync );

no cap, that's the exact signature, spacing and all 💅

---

🦋 ARGUMENTS 🦋

• ubi — the UBI device description object. like, the whole device's little profile card 📇
• aeb — the UBI attach info PEB. this is the PEB in question, the main character of this function ngl 👑
• sync — if it's true, you erase synchronously, like right now, no waiting around. otherwise you schedule it for erasure and let the universe (the work queue) handle it later ⏳
