page_get_link(9)

💅 NAME 💅

Okay bestie, welcome to page_get_link(9) from the Kernel API Manual — literally an implementation of the get_link inode_operation, and it's giving “niche kernel helper that slays.” 💖

---

✨ SYNOPSIS ✨

const char * page_get_link (struct dentry *dentry , struct inode *inode
       , struct delayed_call *callback );

---

🎀 ARGUMENTS 🎀

• dentry — the directory entry that is the symlink. Bestie, it's the symlink's dentry. 🦋
• inode — the inode for the symlink. Yep, that inode. ✨
• callback — used to drop the reference to the symlink. It's the cleanup callback, no cap. 🧹

---

🦋 DESCRIPTION 🦋

Filesystems which store their symlinks in the page cache should use this to implement the get_link member of their inode_operations. Like, if your symlinks live in the page cache, this is the helper you want for that get_link slot. Periodt. 💅

---

🌸 RETURN 🌸

A pointer to the NUL-terminated symlink. That's the whole return vibe. 🌈
