dirty_cow_znode(9)

💅 dirty_cow_znode(9) — Kernel API Manual vibes ✨

okay so bestie, this is the dirty_cow_znode(9) page from the Kernel API Manual, and it's giving “make sure a znode is not being committed” energy. Lowkey specific, highkey important. 🫶

🎀 NAME 🎀

dirty_cow_znode — ensure a znode is not being committed.

✨ SYNOPSIS ✨

struct ubifs_znode * dirty_cow_znode (struct ubifs_info *c , struct ubifs_zbranch *zbr );

🌸 ARGUMENTS 🌸

• c — the UBIFS file-system description object. It's the context bestie, the whole file-system situation.
• zbr — the branch of znode to check. Yes, that exact branch. We're checking it. 💅

🦋 DESCRIPTION 🦋

So the way this works: it returns the dirtied znode on success, or a negative error code on failure. That's the whole plot. On success you get the dirtied znode back; on failure it's a negative error code, no cap. 😭
