gfs2_rename(9)

💅 gfs2_rename(9) — like, the whole manual, but make it make sense

okay bestie, so this is a page from the Kernel API Manual and it's about gfs2_rename — yes, the rename-a-file one. buckle up, it's short but it's iconic 🎀

---

✨ NAME ✨

gfs2_rename — rename a file. that's it, that's the whole vibe. a file gets a new name, we all move on 🌸

---

🦋 SYNOPSIS 🦋

int gfs2_rename (struct inode *odir , struct dentry *odentry , struct
inode *ndir , struct dentry *ndentry );

four arguments, one int coming back at you. no cap, that's the entire signature 🔥

---

👑 ARGUMENTS 👑

okay so every single one of these matters, don't skip:

• odir — the parent directory of the old file name. like, where the file currently lives, its current home base 🏠
• odentry — the old dentry of the file. the previous name's whole situation 💫
• ndir — the parent directory of the new file name. the destination directory, the new neighborhood 🗺️
• ndentry — the new dentry of the file. the fresh name, the glow-up ✨

---

🌈 RETURN 🌈

errno — that's the return value. literally just errno. it's giving "the function tells you how it went" and we respect it 💅
