STRUCT FSCK_DATA(9)

💅 struct fsck_data(9) — the Kernel API Manual, bestie edition 🎀

okay so this page is straight out of the Kernel API Manual and it's literally about struct fsck_data — and no cap, the vibe is "private FS checking information" 👀 like it's the group chat that only the filesystem-check code gets to be in, and everyone else is left on read 🙈

---

✨ NAME ✨

struct fsck_data — private FS checking information 💖

like, it's the little data blob that FS checking keeps to itself. private. exclusive. main character energy fr fr 👑

---

🦋 SYNOPSIS 🦋

struct fsck_data {
    struct rb_root inodes;
 };

that's the whole thing. one member. minimalist icon behavior honestly ✨ (and yes, keep that trailing space-before-brace exactly as it is, iykyk 💅)

---

🌸 Members 🌸

• inodes — RB-tree of all inodes (contains struct fsck_inode objects) 🌈 so it's a red-black tree holding every inode in the game, and each node in there is a struct fsck_inode. it's giving very organized, very balanced, very slay 🫶
