validate_inode(9)

💅 validate_inode(9)

okay so bestie, you've wandered into the Kernel API Manual — specifically the validate_inode(9) page — and honestly? it's a little baddie of a helper function and I'm obsessed. let's get into it 🎀

---

✨ NAME ✨

validate_inode — validate inode. that's it, that's the whole vibe check 👑

---

🦋 SYNOPSIS 🦋

int validate_inode (struct ubifs_info *c , const struct inode *inode );

literally just the one call, no cap 💅

---

🌸 ARGUMENTS 🌸

• c — the UBIFS file-system description object 🗂️ like, the whole file system's little personality profile
• inode — the inode to validate. this is the one getting the vibe check, bestie 🫶

---

💖 DESCRIPTION 💖

so this is a helper function for ubifs_iget, okay? think of it as the bouncer at the club door 🚪✨ it takes a newly built inode and validates various fields of it — making sure they contain sane values and preventing possible vulnerabilities. like it's literally protecting you, no cap 🛡️

returns zero if the inode is all right, and a non-zero error code if it's not. zero = slay, non-zero = not slay 😭

fr fr, don't skip the check — sane values only in this house 🏠💅
