here’s the exact summoning spell, no cap:

int wear_leveling_worker (struct ubi_device *ubi , struct ubi_work *wrk
, int shutdown );

🎀 ARGUMENTS 🎀

• ubi — UBI device description object. it’s the device description object, slay 🫶
• wrk — the work object. literally the work object, that’s the whole vibe 🧚
• shutdown — non-zero if the worker has to free memory and exit because the WL-subsystem is shutting down. so if it’s non-zero, the worker has to free memory and exit because the WL-subsystem is shutting down 🚪💨

💅 DESCRIPTION 💅

okay so the plot: this function copies a more worn out physical eraseblock to a less worn out one. it’s giving wear-leveling glow-up, periodt 🔥
