💅 v9fs_vfs_link — Kernel API Manual ✨

okay so bestie, we're diving into v9fs_vfs_link(9) today and honestly? it's giving "small function, big responsibilities." this is the 9p filesystem's hardlink girlie 🎀

---

🌸 NAME 🌸

v9fs_vfs_link — create a hardlink. that's it, that's the whole vibe. one file, two names, no cap 💖

---

✨ SYNOPSIS ✨

int v9fs_vfs_link (struct dentry *old_dentry , struct inode *dir ,
struct dentry *dentry );

like, literally three args and she returns an int. iconic behavior tbh 👑

---

🦋 ARGUMENTS 🦋

• old_dentry — the dentry for the file you wanna link to, i.e. the original main character 🫶
• dir — the inode that's the destination for the new link. this is where the new name is gonna live, bestie 🏠
• dentry — the dentry for the link itself. that's the new name stepping into the group chat 💅
