gfs2_unlink(9)

🌸 gfs2_unlink(9) 🌸

okay bestie, so this is a page from the Kernel API Manual — the gfs2_unlink(9) one — and honestly? it's a short one, but it's lowkey the moment where a file gets yeeted out of existence, so like, respect it 💅

---

✨ NAME ✨

gfs2_unlink — unlink an inode (and yeah, it does rmdir as well, it's a multitasker, we stan 👑)

---

🦋 SYNOPSIS 🦋

int gfs2_unlink (struct inode *dir , struct dentry *dentry );

---

🎀 ARGUMENTS 🎀

• dir — the inode of the directory that's holding the inode you wanna unlink. like, the folder it lives in, that one 🏠
• dentry — the file itself. the actual main character of this whole situation 🌟

---

💖 DESCRIPTION 💖

so the way this works is genuinely kind of iconic — the routine peeks at the type of the inode and uses that as its little flag 🚩 to figure out whether this call is an unlink or an rmdir. one function, two destinies, no cap. it checks the vibe (the inode type) and then commits to it 💀✨

🌈 RETURN 🌈

errno 🫶
