💅 simple_offset_rename_exchange — exchange rename with directory offsets

okay bestie, welcome to the Kernel API Manual ✨ this one's a lil function with a big name and honestly? she's an icon. no cap.

---

🌸 NAME 🌸

simple_offset_rename_exchange — exchange rename with directory offsets 🫶

---

⭐ SYNOPSIS ⭐

int simple_offset_rename_exchange (struct inode *old_dir , struct dentry
*old_dentry , struct inode *new_dir , struct dentry *new_dentry );

literally just four args, all of them pointers, and she returns an int. slay. 💅

---

🎀 ARGUMENTS 🎀

• old_dir — the parent of the dentry that's being moved. like, the current home of the thing 🏠
• old_dentry — the dentry being moved. yes queen, get relocated ✈️
• new_dir — the destination parent. the new address, if you will 📬
• new_dentry — the destination dentry. the spot she's landing in 🎯

---

🦋 DESCRIPTION 🦋

so what does she actually do? this API preserves the directory offset values. that's the whole vibe. the offsets stay intact, nothing gets scrambled, we love a consistent queen 👑

one thing though — the caller has to provide appropriate serialization. that's on you, bestie, not her 🙈

as for what she gives back: returns zero on success ✨ otherwise a negative errno is returned — and the rename gets rolled back. so if it goes wrong, she literally undoes it. no messy leftovers, we stan a clean exit 😭💖
