scan_for_master(9)

💅 scan_for_master(9) — from the Kernel API Manual, bestie

okay so picture this: you're deep in ubifs land and you need the master node. this little function is literally the one who finds it. 🎀

---

✨ NAME ✨

scan_for_master — search the valid master node. that's it, that's the whole job. 🕵️‍♀️

---

🌸 SYNOPSIS 🌸

int scan_for_master (struct ubifs_info *c );

---

🦋 ARGUMENTS 🦋

• c — the UBIFS file-system description object. your whole vibe, your whole context, everything lives in here. pass it in, she does the rest. 💖

---

⭐ DESCRIPTION ⭐

so what she actually does: this function scans the master node LEBs and searches for the latest master node. iconic behaviour honestly.

then she tells you how it went:

• returns zero in case of success — slay, we're done, no notes. ✨
• returns -EUCLEAN if the master area is corrupted and requires recovery — yeah so that's the "uh oh, she's damaged, time for recovery" signal. handle it. 🔥
• and a negative error code in case of failure — generic bad-news number, go look it up. 😭

no cap, if you get -EUCLEAN back, the master area is corrupted and recovery is required — that's not a suggestion, that's the whole assignment. 💀
