ubi_find_fm_block(9)

🌸 NAME 🌸

Okay bestie, welcome to the Kernel API Manual page for ubi_find_fm_block(9) — yes, that's the manual name, and yes, it's a whole vibe. This one checks whether a PEB is part of the current Fastmap, periodt. 💅

✨ SYNOPSIS ✨

The signature is literally right here, no cap:

struct ubi_wl_entry * ubi_find_fm_block (const struct ubi_device *ubi ,
       int pnum );

🎀 ARGUMENTS 🎀

• ubi — the UBI device description object. It's giving main character energy. 🫶
• pnum — the physical eraseblock to look for. Go find your PEB, bestie. 🔍

💅 DESCRIPTION 💅

Okay so here's the tea: this function returns a wear leveling object if pnum relates to the current fastmap. Otherwise? It returns NULL. That's it. That's the whole plot. 😭
