add_vol(9)

🦋 add_vol(9) — create and add a new volume 💅

okay so welcome to the add_vol(9) page in the Kernel API Manual, bestie. This is the little function that creates and adds a new volume to ubi_attach_info, and it's giving very "small but important" energy. ✨

🌸 NAME 🌸

add_vol — create and add a new volume to ubi_attach_info. That's the whole vibe.

---

✨ SYNOPSIS ✨

struct ubi_ainf_volume * add_vol (struct ubi_attach_info *ai , int
vol_id , int used_ebs , int data_pad , u8 vol_type , int last_eb_bytes
);

---

🎀 ARGUMENTS 🎀

• ai — the ubi_attach_info object. Main character of the attach-info situation.
• vol_id — the VID of the new volume.
• used_ebs — number of used EBS. Yes, EBS. We keep it exactly as written.

• vol_type — volume type.
