STRUCT NILFS_SUPER_ROOT(9)

💅 struct nilfs_super_root(9)

okay so bestie, we're in the Kernel API Manual today and the star of the show is struct nilfs_super_root — yes that's the literal name, no cap. it's giving "structure of super root" and honestly? iconic. 🎀

✨ NAME ✨

struct nilfs_super_root — structure of super root 🌸

---

🦋 SYNOPSIS 🦋

struct nilfs_super_root {
    __le32 sr_sum;
    __le16 sr_bytes;
    __le16 sr_flags;
    __le64 sr_nongc_ctime;
    struct nilfs_inode sr_dat;
    struct nilfs_inode sr_cpfile;
    struct nilfs_inode sr_sufile;
 };

like, that's the whole vibe right there. copy it exactly, don't be weird about it 💖

👑 Members 👑

• sr_sum — the check sum, bestie. it's literally checking the sum. 🔥
• sr_bytes — byte count of the structure. yes, how many bytes. we love a self-aware struct. ✨
• sr_flags — flags, and they're reserved — so hands off, okay? 🙈
• sr_nongc_ctime — write time of the last segment not for cleaner operation. very specific, very demure. 🎀
• sr_dat — DAT file inode 💜
• sr_cpfile — checkpoint file inode ⭐
• sr_sufile — segment usage file inode 🌈
