💅 gfs2_free_journal_extents — free cached journal bmap info

Okay bestie, welcome to another ✨ Kernel API Manual ✨ moment — this one's straight out of the gfs2 corner of the kernel, and honestly? It's giving cleanup-era icon. 🎀

🌸 NAME 🌸

gfs2_free_journal_extents — free cached journal bmap info. That's it, that's the whole job. She frees. She's cached. She's bmap info. 💖

---

✨ SYNOPSIS ✨

void gfs2_free_journal_extents (struct gfs2_jdesc *jd );

No return value, no drama — it's a void, she doesn't owe you an exit status or anything. 🫶

---

🦋 ARGUMENTS 🦋

• jd — the journal 🗒️✨. Literally that's the whole description: the journal. Lowkey the most chill argument spec ever written, ngl.

Heads up babe: this page keeps it very brief — the original gives us the name, the signature, one argument tagged as "the journal", and that glorious SEE ALSO wall. No extra behaviour notes, no warnings, no bugs section. So we're not inventing any. 🙈

That's the whole vibe check, bestie — brought to you from ./fs/gfs2 in the October 2026 edition of the Kernel API Manual. Slay, stay cached, and free those extents responsibly. 💅✨🎀🦋💖
