nilfs_ioctl_getversion(9)

📦 version 7.3.1, in nixpkgs unstable

💅 nilfs_ioctl_getversion(9) — the Kernel API Manual one, bestie 🦋

okay so this is a kernel API page, from the Kernel API Manual, and it's about nilfs_ioctl_getversion — the little function that hands you the tea on a file's version (aka its generation number) 👑

✨ NAME ✨

nilfs_ioctl_getversion — get info about a file's version (generation number) 🎀

yes. that's literally the whole personality. it gets version info. and it slays at it.

🌸 SYNOPSIS 🌸

int nilfs_ioctl_getversion (struct inode *inode , void __user *argp );

that's the whole signature, no cap — returns an int, takes two args, done 💅

💖 ARGUMENTS 💖

  • inode — inode object 🧚 like, the inode itself, the actual file-thing we're being nosy about
  • argp — userspace memory where the generation number of inode is stored 🍓 ok so this is the spot in userspace where the generation number of inode gets stored. girl, it's pointing at userspace memory, k?

🌈 RETURN 🌈

  • 0 on success 🎉 slay
  • -EFAULT on error 😭 and that's it, that's the whole error list — no extras, no surprises
so like… if it's not 0 it's -EFAULT. the vibe check is very simple here.

👑 SEE ALSO 👑

and now the group chat roll call 📞 — the kernel file ./fs/nilfs2/ioctl.c plus every single one of these icons:

like, the entire nilfs2 ioctl friend group fr fr 🫶 iykyk

anyway that's the page, mwah 💋 — straight from ./fs/nilfs2, dated October 2026, and yes the manual section is nilfs_ioctl_getversion(9) because we keep it consistent, periodt ✨
