simple_rename_timestamp(9)

✨ simple_rename_timestamp(9) ✨

okay so bestie, welcome to the kernel API manual, this one's simple_rename_timestamp(9) — the little helper that handles all your rename timestamp drama 💅

---

🌸 NAME 🌸

simple_rename_timestamp — update the various inode timestamps for rename ✨

---

🎀 SYNOPSIS 🎀

void simple_rename_timestamp (struct inode *old_dir , struct dentry
*old_dentry , struct inode *new_dir , struct dentry *new_dentry );

---

🦋 ARGUMENTS 🦋

• old_dir — the old parent directory, like where the thing was living before 🏠
• old_dentry — the dentry that is being renamed, aka the main character of this whole operation 👑
• new_dir — the new parent directory, its new address fr fr 📦
• new_dentry — the target for rename 🎯

---

💖 DESCRIPTION 💖

so POSIX literally mandates this, no cap: the old and new parent directories both gotta have their ctime and mtime updated ⏰✨

and also — the inodes of old_dentry and new_dentry (if there even is one, like, if any) get their ctime updated too 💫

that's it, that's the whole vibe check 🫶
