📦 version 7.3.1, in nixpkgs unstable

💖 struct nilfs_sufile_info(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ — this one's all about struct nilfs_sufile_info, and honestly? it's giving "private data" in the cutest way possible. let's get into it 🎀

🌸 NAME 🌸

struct nilfs_sufile_info — the on-memory private data of sufile, no cap 💅

✨ SYNOPSIS ✨

here's the whole vibe, literally copy-paste this exactly:

struct nilfs_sufile_info {
    struct nilfs_mdt_info mi;
    unsigned long ncleansegs;
    __u64 allocmin;
    __u64 allocmax;
 };

🦋 Members 🦋

okay so every single field, one by one, and yes we're doing all of them 🫶

  • mi — the on-memory private data of the metadata file. it's the main character of this struct ngl 👑
  • ncleansegs — the number of clean segments. that's it, that's the whole field 💖
  • allocmin — the lower limit of the allocatable segment range. lowkey the floor of the whole situation 🙈
  • allocmax — the upper limit of the allocatable segment range. highkey the ceiling, periodt 🔥

🌈 SEE ALSO 🌈

so many friends in the Kernel file, iykyk 💜 the file is ./fs/nilfs2/sufile.c and it's linked up with literally all of these:

🫶 and that's the whole page bestie, you ate that 💅

okay so this one lives in ./fs/nilfs2, the manual's dated October 2026, and it's literally the struct nilfs_sufile_info(9) entry — iconic, no notes 🦋✨
