scan_dirty_idx_cb(9)

💅 scan_dirty_idx_cb(9) — bestie edition 🎀

Okay so real quick before we dive in: this is a page from the Kernel API Manual, and it's all about scan_dirty_idx_cb — a callback that the scan for a dirty index LEB uses. Yes, that's the whole vibe. Let's go ✨

---

🌸 NAME 🌸

scan_dirty_idx_cb — literally just the callback that the scan for a dirty index LEB uses. That's it, that's the function 🫶

---

✨ SYNOPSIS ✨

int scan_dirty_idx_cb (struct ubifs_info *c , const struct ubifs_lprops
*lprops , int in_tree , void *arg );

She takes four arguments and returns an int. Iconic behavior honestly 👑

---

🎀 ARGUMENTS 🎀

• c — the UBIFS file-system description object. The whole fs, in object form 💖
• lprops — the LEB properties to scan. Like, the actual props being looked at.
• in_tree — whether the LEB properties are in main memory. Yes/no energy 🌈
• arg — information passed to and from the caller of the scan. Note that it goes both ways — it's giving main character bidirectional communication 💅

---

💜 DESCRIPTION 💜

So what does this function do? It returns a code, and that code tells you which of three things is happening:

1. Whether the scan should continue — LPT_SCAN_CONTINUE ✨
2. Whether the LEB properties should be added to the tree in main memory — LPT_SCAN_ADD 🌸
3. Whether the scan should stop — LPT_SCAN_STOP 💀

Three constants, three moods. Pick your fighter. No cap, that's the entire description 🙈
