💅 kernfs_rename_ns(9)

okay so welcome to the Kernel API Manual bestie, today we're reading the kernfs_rename_ns(9) page and honestly? she's short, she's sweet, she moves nodes and renames them in one go. main character energy fr fr 🌸

---

✨ NAME ✨

kernfs_rename_ns — move and rename a kernfs_node 🦋

yes. both. one function. she does it all 💅

---

✨ SYNOPSIS ✨

int kernfs_rename_ns (struct kernfs_node *kn , struct kernfs_node *new_parent , const char *new_name , const struct ns_common *new_ns );

---

✨ ARGUMENTS ✨

• kn — the target node 👑 like, the node we're actually doing stuff to
• new_parent — the new parent to put sd under 🫶 (yes, the page says sd, we don't question the lore, we just pass it along)
• new_name — the new name, literally just the name she's getting 🎀
• new_ns — the new namespace tag 🏷️

---

✨ RETURN ✨

0 on success, -errno on failure. that's the whole vibe check — zero means slay, negative errno means something went off 😭

---

✨ SEE ALSO ✨
