💖 ubi_do_get_device_info — the Kernel API Manual, bestie edition 💖

okay so this is ubi_do_get_device_info(9), live from the Kernel API Manual, and honestly? it's a little ✨niche✨ but we're gonna slay it together fr fr.

🌸 NAME 🌸

ubi_do_get_device_info — literally just getting info about a UBI device. that's the whole vibe. 💅

---

🎀 SYNOPSIS 🎀

void ubi_do_get_device_info (struct ubi_device *ubi , struct
       ubi_device_info *di );

like, that's the signature, bestie. don't @ me, that IS the formatting. 🫶

---

🦋 ARGUMENTS 🦋

• ubi — the UBI device description object 👑 (yes, the main character here)
• di — this is where the information gets stored. it's giving "empty cup, pour the tea into it" 🍓

---

⭐ DESCRIPTION ⭐

so here's the tea: this function is the same as ubi_get_device_info, no cap. but — and this is the important part, don't skip it — it assumes the UBI device is locked and cannot disappear. 😭 like, it just trusts you on that. so bestie, please actually hold that lock, ok? iykyk.

lowkey a vibe check on your locking discipline. the function is not gonna check for you. 🙈
