STRUCT GLUEBI_DEVICE(9)

✨ struct gluebi_device(9) — from the Kernel API Manual ✨

okay bestie, buckle up 💅 this is a page straight out of the Kernel API Manual, and it's all about struct gluebi_device — literally the gluebi device description data structure. that's the whole vibe. it's giving "small struct, big responsibilities" 🫶

🌸 SYNOPSIS 🌸

here's the whole thing, character for character, no cap:

struct gluebi_device {
    struct mtd_info mtd;
    int refcnt;
    struct ubi_volume_desc *desc;
    int ubi_num;
    int vol_id;
    struct list_head list;
 };

look at her. six fields. main character energy fr fr ✨

🎀 Members 🎀

• mtd — the emulated MTD device description object 💖 this is the whole point of the struct, lowkey.
• refcnt — the gluebi device reference count. it's counting refs, bestie, that's what it does 🔥
• desc — the UBI volume descriptor 👑
• ubi_num — the UBI device number that this gluebi device works on 🦋
• vol_id — the ID of the UBI volume that this gluebi device works on 🌸
• list — its link in a list of gluebi devices. she's connected. she's in the group chat 🫶

💜 SEE ALSO 💜

if you're obsessed with this struct (and honestly? same), the kernel file lives at ./drivers/mtd/ubi/gluebi.c, and you're gonna wanna go read these too:

• find_gluebi_nolock(9)
• gluebi_get_device(9)
• gluebi_put_device(9)
• gluebi_read(9)
• gluebi_write(9)
• gluebi_erase(9)
• gluebi_create(9)
• gluebi_remove(9)
• gluebi_updated(9)
• gluebi_resized(9)
• gluebi_notify(9)

like, the whole friend group 😭 go say hi.

ngl, that's the entire page — no hidden lore, no secret flags, no warnings. sometimes a struct is just a struct and that's iconic 💅

anyway, this lil chapter of the Kernel API Manual comes to you from ./drivers/mtd/ubi, dated October 2026 — mwah, bye bestie, go read your kernel source 🍓🧚‍♀️💖
