check_av(9)

💅 NAME 💅

okay so this is check_av(9) from the Kernel API Manual, and it's literally here to check volume attaching information. That's the whole assignment, bestie — short, iconic, to the point. ✨

🌸 SYNOPSIS 🌸

int check_av (const struct ubi_volume *vol , const struct
ubi_ainf_volume *av );

🎀 ARGUMENTS 🎀

• vol — the UBI volume description object. Like the volume's little ID card 🪪
• av — the volume attaching information. The receipts it's attaching with 💌

✨ DESCRIPTION ✨

okay so here's the tea: this function returns zero if the volume attaching information is consistent to the data read from the volume tabla, and -EINVAL if not. That's it — no extra drama, just a consistency vibe check. And yes, if it fails, -EINVAL is the red flag 🚩
