ceph_present_ino(9)

✨ ceph_present_ino(9) ✨

okay so bestie, welcome to the Kernel API Manual — today's main character is ceph_present_ino, and honestly? she's a tiny little helper with one very specific job 💅

---

💖 NAME 💖

ceph_present_ino — formats an inode number so it can be presented to userland 🎀

---

🌸 SYNOPSIS 🌸

u64 ceph_present_ino (struct super_block *sb , u64 ino );

---

🦋 ARGUMENTS 🦋

• sb — the superblock where the inode lives, like its whole address fr fr 🏠
• ino — the inode number we're gonna (maybe) convert 👀

---

✨ DESCRIPTION ✨

okay so picture this: if the user mounted with the ino32 option, then that 64-bit value needs to be converted into something that actually fits inside 32 bits 😭 like it's giving "too big for the box" energy.

and here's the tea 🍵 — internal kernel code never uses this value. not once. so this whole function is entirely for userland consumption, periodt. it's literally just doing a little presentation glow-up for the userspace girlies 💅✨

and that's the whole vibe, bestie 🌈 this iconic little page came from ./fs/ceph, dated October 2026 — mwah, slay, no cap 💖🎀🦋
