STRUCT NILFS_CPSTAT(9)

🌸 struct nilfs_cpstat(9) 🌸

okay bestie, welcome to the Kernel API Manual corner of the internet 💖 this one's short, sweet, and honestly kind of a serve — we're talking about struct nilfs_cpstat, aka the lil stats blob for checkpoints. no cap, it's tiny. let's get into it 🎀

---

✨ NAME ✨

struct nilfs_cpstat — checkpoint statistics 🦋

like, literally just checkpoint statistics. that's the whole vibe check, and it passed 💅

---

🧚 SYNOPSIS 🧚

ok so deep breath, here's the whole struct, and yes you can just read it, it's not that deep:

struct nilfs_cpstat {
    __u64 cs_cno;
    __u64 cs_ncps;
    __u64 cs_nsss;
 };

three __u64s. that's it. that's the struct. main character energy from a very small cast 😭👑

---

💜 Members 💜

• cs_cno — the checkpoint number 🔢 like, which checkpoint are we even talking about, yk?
• cs_ncps — number of checkpoints 👑 the actual count, fr fr
• cs_nsss — number of snapshots 🌸 yes it's nsss with three s's, no I did not make that up, yes it's iconic

🫶 SEE ALSO 🫶

the whole friend group lives in the kernel file ./include/uapi/linux/nilfs2_api.h — go say hi to all of them 💖:

• struct nilfs_cpinfo(9)
• struct nilfs_suinfo(9)
• struct nilfs_suinfo_update(9)
• struct nilfs_cpmode(9)
• struct nilfs_argv(9)
• struct nilfs_period(9)

• struct nilfs_vinfo(9)
• struct nilfs_vdesc(9)
• struct nilfs_bdesc(9)

ngl that's a whole squad 🧚✨

lowkey a reminder: this is a struct of __u64 fields, so it's checkpoint statistics and nothing else — no hidden extras, no secret lore, just the numbers 🙈
