vdo_load_super_block(9)

💖 NAME 💖

okay bestie, meet vdo_load_super_block(9) from the Kernel API Manual — it's the function that does the whole allocate-a-super-block-and-read-its-contents-from-storage thing, and yes the manual name is folded right in here like a cute little bow 🎀.

vdo_load_super_block — Allocate a super block and read its contents from storage.

✨ SYNOPSIS ✨

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

🫶 ARGUMENTS 🫶

• vdo — the vdo that's holding the super block on disk. Like, that's where the super block lives, bestie 💾.
• parent — the completion to notify after loading the super block. It's the one that gets the heads-up when the load is done 🫶.
