vdo_encode_volume_geometry(9)

💅 NAME ✨

okay bestie, welcome to the Kernel API Manual page for vdo_encode_volume_geometry(9) — and it's literally here to encode the on-disk representation of a volume geometry into a buffer. Slay. 🦋

🦋 SYNOPSIS 🦋

int vdo_encode_volume_geometry (u8 *buffer , const struct
       volume_geometry *geometry , u32 version );

🎀 ARGUMENTS 🎀

• buffer — a buffer to store the encoding. That's its whole assignment, bestie. 💾
• geometry — the geometry to encode. Give it a moment, it's the main character here. 🎀
• version — the geometry block version to encode. Pick the version, no cap. 🦋

✅ RETURN ✅

Returns VDO_SUCCESS or an error. That's the vibe check, periodt. ✅💀
