create_ok(9)

💫 create_ok(9) 💫

okay so bestie, welcome to the Kernel API Manual — yes we're in the kernel docs now, main character energy only 💅. Today's episode: create_ok, a function that literally just answers the question "is it chill to make a new on-disk inode here?" 🦋

---

✨ NAME ✨

create_ok — OK to create a new on-disk inode here?

Like, that's the whole vibe check. It checks whether you're allowed to create. That's it. That's the function. 🎀

---

🌸 SYNOPSIS 🌸

int create_ok (struct gfs2_inode *dip , const struct qstr *name ,
umode_t mode );

Look at her. Three params, one int return, zero chill. 🫶

---

🧚 ARGUMENTS 🧚

• dip — the directory where the dinode is gonna live. Think of it as the folder you're moving into 🏠✨
• name — the name of the new dinode. its whole identity, no pressure 💀
• mode — honestly? the manpage gives us nothing here. blank. empty. the original left it totally undescribed and I'm not about to invent lore 🙈 so: mode, with no description. iconic behaviour, honestly 👑

---

🔥 RETURN 🔥

errno

that's it. that's the return section. errno. slay, I guess 💅

ngl bestie, no warnings, no bugs section, no exit-status drama on this one — it's a short and sweet little page. read it, love it, move on 🍓

kisses and cross-references, this page came to you from ./fs/gfs2, dated October 2026 — and it's signed off as create_ok(9) because obviously 💖✨🎀
