💫 jbd2_journal_wipe(9) 💫

okay bestie, buckle up, we're in the kernel API manual rn — this is a page from the Kernel API Manual, and no cap it's actually kind of a big deal 🎀

✨ NAME ✨

jbd2_journal_wipe — wipe journal contents, like, the whole thing 💅

---

🦋 SYNOPSIS 🦋

int jbd2_journal_wipe (journal_t *journal , int write );

---

🌸 ARGUMENTS 🌸

• journal — the journal you're acting on. main character, literally.
• write — a flag, and bestie the details are right below 👇

---

💖 DESCRIPTION 💖

So what this does is wipe out all of the contents of a journal. Safely. Iconic behavior honestly.

The way that it also produces a warning if the journal contains any valid recovery information. so like, heads up 🫶

🚨 fr fr: this must be called between journal_init_*() and jbd2_journal_load. don't be out here calling it whenever, that's not the vibe.

And here's the tea on the write flag:

• If write is non-zero, then we wipe out the journal on disk. like, actually gone, on the disk, periodt.
• Otherwise — if it's zero — we merely suppress recovery. way more chill, lowkey.
