copy_znode(9)

💅 copy_znode(9) — the Kernel API Manual girlies know

okay so bestie, welcome to copy_znode(9) — that's the manual page, and the manual it lives in is the Kernel API Manual. buckle up, this one's short but it's important ✨

---

🌸 NAME

copy_znode — copy a dirty znode.

like, literally just copy a dirty znode. that's the whole gig. iconic honestly.

---

🦋 SYNOPSIS

struct ubifs_znode * copy_znode (struct ubifs_info *c , struct
ubifs_znode *znode );

she takes two things and gives you back a struct ubifs_znode * — slay 💅

---

🎀 ARGUMENTS

• c — the UBIFS file-system description object 🗂️ your whole vibe context, basically
• znode — the znode to copy. the one getting the dupe treatment 🫶

---

✨ DESCRIPTION

so here's the tea ☕: a dirty znode that's being committed may not be changed. that's the rule, no cap, do not touch. so instead of messing with the original, she just copies it. copy > chaos. periodt 💖
