end_dirop(9)

🦋 end_dirop(9) 🦋

okay bestie, welcome to the Kernel API Manual corner — this one is tiny but iconic. The main character is end_dirop, and she signals completion of a dirop. 💅

---

🌸 NAME 🌸

end_dirop — signal completion of a dirop. periodt. ✨

---

✨ SYNOPSIS ✨

void end_dirop (struct dentry *de );

---

🎀 ARGUMENTS 🎀

• de — the dentry which was returned by start_dirop or similar. she’s literally the one we’re wrapping up here. 💖

---

💅 DESCRIPTION 💅

so here’s the tea: if de is an error, nothing happens — no cap, not a single thing. Otherwise, any lock taken to protect the dentry gets dropped, and the dentry itself is released (dput). that’s the whole vibe. 🫶
