Okay bestie, listen up ✨ — this one lives in the Kernel API Manual, and it's a lil function called vdo_decode_slab_journal_entry, and honestly? It does exactly one thing and does it iconically. 💖

🌸 NAME 🌸

vdo_decode_slab_journal_entry — decode a slab journal entry. That's it, that's the whole personality. 🫶

struct slab_journal_entry vdo_decode_slab_journal_entry (struct
       packed_slab_journal_block *block , journal_entry_count_t entry_count );

It takes a block and an entry_count, and hands you back a struct slab_journal_entry. Short king behavior honestly 👑 no cap.
