dirty_cow_nnode(9)

💅 dirty_cow_nnode — like, the whole manual, bestie

okay so this is dirty_cow_nnode(9) from the Kernel API Manual — yes it's a section 9 page, yes it's niche, no we are not skipping a single line of it 🫶

---

✨ NAME ✨

dirty_cow_nnode — the whole entire job of this one is making sure an nnode is not being committed, no cap 💅

---

🌸 SYNOPSIS 🌸

struct ubifs_nnode * dirty_cow_nnode (struct ubifs_info *c , struct
ubifs_nnode *nnode );

like, it hands you back a struct ubifs_nnode *, and it takes those two args ↑ that's it that's the vibe 🎀

---

🦋 ARGUMENTS 🦋

• c — the UBIFS file-system description object, literally the whole filesystem's little passport okay 🛂
• nnode — the nnode to check, the main character of this function fr fr 👑

---

⭐ DESCRIPTION ⭐

Returns the dirtied nnode on success ✨ or a negative error code on failure 😭 that's literally the whole description, she's concise and she's iconic.

no cap: success gives you the dirtied nnode back, failure gives you a negative error code. those are the only two outcomes, periodt.
