vdo_parse_geometry_block(9)

💅 NAME 💅

okay so bestie, welcome to the Kernel API Manual, section 9 — this one's vdo_parse_geometry_block, and it's giving decoder girlie ✨

vdo_parse_geometry_block — decode and validate an encoded geometry block. that's it, that's the whole job, and she does it flawlessly 💖

✨ SYNOPSIS ✨

int vdo_parse_geometry_block (u8 *block , struct volume_geometry *geometry );

like yes, two arguments, one int coming back at you, no cap 🫶

🎀 ARGUMENTS 🎀

• block — the encoded geometry block. this is the raw little guy you're handing over to get read 👑
• geometry — the structure that receives the decoded fields. she's the empty container, and she is about to be filled with truth 🦋

🌈 SEE ALSO 🌈

bestie, the friend group is huge, lowkey iconic. also worth noting the kernel file this all lives in: ./drivers/md/dm-vdo/encodings.c 📁

ngl the whole squad showed up for this one 💀 read them all, iykyk 🌸

okay that's the page!! mwah 💜 this little beauty lives in ./drivers/md/dm-vdo, stamped October 2026, and yes she's still called vdo_parse_geometry_block(9) — periodt 🎀✨
