add_corrupted(9)

💅 add_corrupted(9) — a Kernel API Manual moment

okay so bestie, welcome to add_corrupted(9), straight out of the Kernel API Manual ✨ this one lives in the kernel, and it's all about one very specific little job: shoving a corrupted physical eraseblock into the list of corrupted things. iconic honestly 🎀

---

🌸 NAME

add_corrupted — add a corrupted physical eraseblock 🫶

---

⭐ SYNOPSIS

int add_corrupted (struct ubi_attach_info *ai , int pnum , int ec );

---

🦋 ARGUMENTS

• ai — attaching information, the whole vibe context you're working in 💫
• pnum — physical eraseblock number to add, like literally which one 📌
• ec — the erase counter of that physical eraseblock, bestie 🔢

---

💖 DESCRIPTION

so what this function does is: it allocates a 'struct ubi_ainf_peb' object for a corrupted physical eraseblock pnum, and adds it to the 'corr' list. periodt 💅

the corruption was presumably not caused by a power cut — that's the assumption we're rolling with here, no cap 😌

returns zero in case of success and a negative error code in case of failure. that's the whole deal, slay 🌈
