ensure_wear_leveling(9) 💅

okay so welcome to the Kernel API Manual, bestie — today's main character is ensure_wear_leveling(9), and it's literally here to handle the “schedule wear-leveling if it is needed” situation. no cap.

🌸 NAME 🌸

ensure_wear_leveling — schedule wear-leveling if it is needed.

✨ SYNOPSIS ✨

int ensure_wear_leveling (struct ubi_device *ubi , int nested );

🎀 ARGUMENTS 🎀

• ubi — UBI device description object. iconic descriptor behavior, honestly.
• nested — set to non-zero if this function is called from UBI worker. iykyk.

🦋 DESCRIPTION 🦋

so the whole vibe is: this function checks if it is time to start wear-leveling, and if yes, it schedules it. that's the move. periodt.

and the return sitch? this function returns zero in case of success and a negative error code in case of failure. so 0 = good, negative = not the moment 😭.
