vdo_open_recovery_journal(9)

✨ vdo_open_recovery_journal(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 this one's a vdo_open_recovery_journal(9) situation, and honestly? it's giving "small function, big responsibility" energy. let's get into it 🫶

---

🌸 NAME 🌸

vdo_open_recovery_journal — literally just prepare the journal for new entries. that's it. that's the whole vibe. the journal gets opened up and made all ready to accept new entries, and then it goes off to do journal things. iconic 💖

---

🦋 SYNOPSIS 🦋

void vdo_open_recovery_journal (struct recovery_journal *journal ,
struct slab_depot *depot , struct block_map *block_map );

note the return type: void. it returns nothing, bestie. no cap, it just does the thing and leaves. no exit status drama, no "did it work" — it's not that kind of function 😌

---

🎀 ARGUMENTS 🎀

so you're passing in three things, and yes, you need all of them:

• journal — the journal in question 💫 like, the journal. the one we're opening. the main character, honestly.
• depot — the slab depot for this VDO. it's the depot. for this VDO. very demure, very mindful 🧚
• block_map — the block map for this VDO. again: for this VDO. we love a consistent scope ✨
