gfs2_statfs(9)

🦋 gfs2_statfs(9) — the Kernel API Manual said "let me introduce you" 🦋

okay bestie, gather round, because this one is a tiny little function in the Kernel API Manual and honestly? it's giving "small but mighty" 💅

---

✨ NAME ✨

gfs2_statfs — literally just gathers stats about the filesystem and hands them back to you. that's it. that's the whole vibe. 🎀

---

✨ SYNOPSIS ✨

int gfs2_statfs (struct dentry *dentry , struct kstatfs *buf );

lowkey iconic signature ngl — one dentry in, one buffer out, one int of truth. 🫶

---

✨ ARGUMENTS ✨

• dentry — "The name of the link" 💫 like yes bestie, this is the dentry you're asking about, the actual name-of-the-link situation.
• buf — "The buffer" 🌸 that's where the stats land. the little vessel. the container. the buffer, if you will. 😭

---

✨ RETURN ✨

0 on success, or an error code 🔥 so like — zero means slay, anything else means the vibe check failed and you got an error code instead. no cap.

fr fr check the return value, bestie. 0 is the good timeline, everything else is the plot twist. 💀
