next_dirty_cnode(9)

💅 next_dirty_cnode(9) — like, the Kernel API Manual bestie ✨

okay so real talk, this is a page straight out of the Kernel API Manual — section 9, kernel-level grind, no big deal 🎀

---

🌸 NAME 🌸

next_dirty_cnode — find next dirty cnode. that's it. that's the whole vibe 💖

---

✨ SYNOPSIS ✨

struct ubifs_cnode * next_dirty_cnode (const struct ubifs_info *c ,
struct ubifs_cnode *cnode );

literally the whole signature, copy it exactly, don't @ me 🫶

---

🦋 ARGUMENTS 🦋

• c — the UBIFS file-system description object. yeah she's the whole filesystem in a struct, main character energy fr 👑
• cnode — the cnode you start searching from. your starting point, your launchpad, your beginning bestie 💫

---

💀 DESCRIPTION 💀

so this function returns the next dirty cnode 🧚 and if there isn't one? it returns NULL. that's it. that's the tea. no cap, no extra lore, no secret behaviour — NULL when there's nothing dirty left to find 🙈
