start_creating_noperm(9)

💅 start_creating_noperm — like, the Kernel API Manual actually has a page for this 🎀

okay so bestie, this is start_creating_noperm(9) from the Kernel API Manual and I need you to sit with me for a sec because this little function is that girl 💖

---

✨ NAME ✨

start_creating_noperm — get everything prepped to create a given name, but without the permission checking, iykyk 🫶

---

🌸 SYNOPSIS 🌸

struct dentry * start_creating_noperm (struct dentry *parent , struct qstr *name );

look at her. so demure. so c-c-clean ✨

---

🦋 ARGUMENTS 🦋

• parent — the directory where you're getting ready to create the name 💅 like, this is the vibes-holder, the folder, the whole location of it all
• name — the actual name you wanna create 🎀 literally the thing itself

---

👑 DESCRIPTION 👑

okay so here's the tea, bestie: locks get taken and a lookup gets performed before an object gets created in a directory 🔥 that's the whole ritual, no cap.

And if the name already exists? You get a positive dentry back. That's it, that's the outcome — she's already there, she's thriving, move on 💀

---

⭐ RETURN ⭐

you get back a negative dentry or a positive dentry, or an error 😭 that's the whole range, that's the vibe check.
