vdo_save_geometry_block(9)

💾 vdo_save_geometry_block(9) — the kernel API manual, but make it cute 🎀

okay so bestie, welcome to the vdo_save_geometry_block(9) page from the Kernel API Manual 💖 this one is literally all about encoding the vdo and saving the geometry block asynchronously. no cap, it's giving "background task realness" ✨

🌸 NAME 🌸

vdo_save_geometry_block — Encode the vdo and save the geometry block asynchronously.

like, it does exactly what it says on the tin, bestie 💅

✨ SYNOPSIS ✨

void vdo_save_geometry_block (struct vdo *vdo , struct vdo_completion
*parent );

that's the whole signature, periodt 🫶

🦋 ARGUMENTS 🦋

• vdo — The vdo whose state is being saved. this is the main character of the operation 👑
• parent — The completion to notify when the save is complete. basically the "hey bestie, we're done here" callback 💌

okay and finally, the cute little sign-off 🎀 this page lives in the ./drivers/md/dm-vdo directory (that's the source, bestie), and it's dated October 2026. so like, from the future, literally iconic ✨ bye bestie, go save that geometry block asynchronously 💅🦋
