✨ gfs2_get_link(9) ✨

okay so bestie, welcome to the gfs2_get_link page — it lives in the Kernel API Manual, and it's literally about following a symbolic link. yes, that kind of following. 🦋

---

💅 NAME 💅

gfs2_get_link — Follow a symbolic link

like, that's the whole vibe. it follows the link. it gets the link. it is the link. periodt. 🔥

---

✨ SYNOPSIS ✨

const char * gfs2_get_link (struct dentry *dentry , struct inode *inode
, struct delayed_call *done );

the way this signature just sits there with three arguments and a const char * return... main character energy fr fr. 👑

---

🎀 ARGUMENTS 🎀

• dentry — The dentry of the link. that's the directory entry, the whole "where does this thing even live" situation. lowkey essential. 🌸
• inode — The inode of the link. the actual metadata bestie behind the dentry. iconic duo, no cap. 💖
• done — destructor for return value. yes ma'am, it's a struct delayed_call * and it handles the cleanup when the returned string's time is up. we love a responsible queen. 🧚

---

💜 DESCRIPTION 💜

This can handle symlinks of any size.

that's it. that's the description. short, sweet, and it ate. 💅✨ whether your symlink is tiny or it's giving enormous, gfs2_get_link is not gonna be weird about it. no size-based gatekeeping here. 🫶

---

🌈 RETURN 🌈

0 on success or error code.

so like — 0 means slay, we're good, everything worked. anything else? that's an error code, and you should probably look at it. 😭 not me hoping your return value is 0 every single time. 🙈

ngl, this is what the page says, so this is what you get — 0 on success, or an error code. don't come for me, I'm just the messenger. 💀
