check_inodes(9)

🌸 check_inodes — checks all inodes 🌸

okay so this one is from the Kernel API Manual, section 9 — yes, the big-kid kernel section, we love that for us 🫶

---

✨ NAME ✨

check_inodes — literally just checks all the inodes. that's the whole job. she's a very "no thoughts head empty just verify" icon 💅

---

🎀 SYNOPSIS 🎀

int check_inodes (struct ubifs_info *c , struct fsck_data *fsckd );

---

🦋 ARGUMENTS 🦋

• c — the UBIFS file-system description object. the whole vibe of the filesystem lives in here 🗂️
• fsckd — the FS checking information. all the fsck-y deets go in this one 📋

---

🔥 DESCRIPTION 🔥

okay so picture this: this is a helper function for dbg_check_filesystem, right? and what she does is she walks the RB-tree of inodes after the index scan has finished. like, the scan is done, everybody's seated, and now she's doing the vibe check ✨

and what's she checking? that inode nlink, size, etc. are correct. the etc. is doing a lot of heavy lifting there but that's what the manpage says so we're saying it too, no cap 💀

Returns:

• zero if the inodes are fine — slay, we love a clean run 🌈
• -EINVAL if they're not fine — not slay, something's wrong 😭
• a negative error code in case of failure — like an actual "something broke broke" failure, not just a "validation failed" failure 🙈

bestie please note: "returns zero if inodes are fine, -EINVAL if not, and a negative error code in case of failure" — those are three separate outcomes, don't merge them in your head, i'm begging 🫶
