ubi_get_compat(9)

✨ ubi_get_compat(9) — get compatibility flags of a volume ✨

okay bestie, welcome to the kernel API manual for ubi_get_compat(9), straight out of the ubi corner of the kernel 💖 this one's short and sweet, so let's get into it.

🌸 SYNOPSIS 🌸

int ubi_get_compat (const struct ubi_device *ubi , int vol_id );

🎀 ARGUMENTS 🎀

• ubi — the UBI device description object. like, the whole device's vibe in struct form 💅
• vol_id — the volume ID. which volume are we talking about, bestie?

🦋 DESCRIPTION 🦋

so this function returns the compatibility flags for an internal volume. that's it, that's the whole job ✨

and here's the fun part: user volumes literally have no compatibility flags, so for those you just get 0 back. zero. nada. the void. 🫶
