STRUCT UBIFS_SCAN_LEB(9)

💅 struct ubifs_scan_leb(9) — the Kernel API Manual tea 🎀

okay so bestie, buckle up, because this is a page straight out of the Kernel API Manual ✨ and it's all about struct ubifs_scan_leb — the little icon that holds all the info from a UBIFS scanned LEB 👑 no cap, that's literally what NAME says.

✨ NAME ✨

struct ubifs_scan_leb — UBIFS scanned LEB information 🦋

---

🌸 SYNOPSIS 🌸

struct ubifs_scan_leb {
    int lnum;
    int nodes_cnt;
    struct list_head nodes;
    int endpt;
    void *buf;
 };

🎀 Members 🎀

time for the vibe check on every single field, and yes we're doing all of them 💖

• lnum — the logical eraseblock number 🍓 (like, which LEB are we even talking about, iykyk)
• nodes_cnt — the number of nodes scanned 🔥 that's the count, periodt
• nodes — the list of struct ubifs_scan_node 🌈 (it's a list, she contains scan nodes, that's the whole thing)
• endpt — the end point (and therefore the start of empty space) 🫶 lowkey important, highkey iconic
• buf — the buffer containing the entire LEB scanned 💜 like, the whole LEB, in a buffer, as one treats
