STRUCT UBI_RENAME_ENTRY(9)

💅 struct ubi_rename_entry(9) — the Kernel API Manual tea 🫶

okay so bestie, welcome to the Kernel API Manual page for struct ubi_rename_entry(9), and honestly? it's giving "small struct, big responsibilities." slay. ✨

---

🌸 NAME 🌸

struct ubi_rename_entry — the data structure that describes a volume re-name. literally its whole job. no cap. 💖

---

⭐ SYNOPSIS ⭐

here's the struct, and yes i'm giving it to you exactly as it is because we do not mess with code in this house:

struct ubi_rename_entry {
    int new_name_len;
    char new_name[UBI_VOL_NAME_MAX + 1];
    int remove;
    struct ubi_volume_desc *desc;
    struct list_head list;
 };

that's her. that's the whole girl. iconic. 👑

---

🎀 Members 🎀

okay let's do a little member-by-member vibe check, one at a time, because each one eats 💅

• new_name_len — the length of the new volume name. that's it, that's the whole field, she's just a number holding it down. 🔥
• new_name — the new volume name itself. the actual name. the main character string. 💖
• remove — okay so if this is not zero, this volume should be removed, not re-named. read that again bestie, it's a whole different operation hiding in there 😭 like the field said "rename or nah?" and chose violence.
• desc — the descriptor of the volume. yep. that's the vibe. 🦋
• list — links re-name entries into a list. she's the social one, she connects everybody. 🫶

🦋 Description 🦋

so where does this struct actually get used? in the multiple volume re-name code, periodt.

here's the tea: UBI first creates a list of struct ubi_rename_entry objects from the struct ubi_rnvol_req request object, and then it uses this list to do all the job. all of it. the whole job. no crumbs left. 🔥 like, the request comes in, she gets converted into a lil list of these entries, and then the list does the actual work. teamwork makes the dream work, iykyk. 🌈

💀 friendly reminder: remove being non-zero means remove, not re-name. don't get it twisted bestie, that volume is gone-gone.
