prot_queue_add(9)

✨ prot_queue_add(9) ✨

okay so real talk, this one lives in the Kernel API Manual and it's lowkey one of those tiny functions that keeps your flash memory from getting absolutely cooked 💅

---

🎀 NAME 🎀

prot_queue_add — bestie, this is the one that adds a physical eraseblock to the protection queue 🫶

---

🌸 SYNOPSIS 🌸

void prot_queue_add (struct ubi_device *ubi , struct ubi_wl_entry *e );

---

🦋 ARGUMENTS 🦋

• ubi — the UBI device description object, aka the whole vibe of the device you're messing with
• e — the physical eraseblock you're adding, the actual main character here

---

💖 DESCRIPTION 💖

so here's the tea ☕ this function takes e and drops it at the tail of the protection queue ubi->pq. iconic behavior, no notes.

once it's in there, e just chills for UBI_PROT_QUEUE_LEN erase operations and gets temporarily protected from the wear-leveling worker. like, she's on a little vacation, do not perceive her 💅✨

⚠️ okay but fr fr, note this: wl->lock has to be locked. that's not a suggestion, that's the whole assignment. don't skip it 😭
