✨ kiocb_modified(9) ✨

okay so this is a page straight out of the Kernel API Manual, bestie — like, the actual kernel docs, and we're gonna get through it together 💖

---

🌸 NAME 🌸

kiocb_modified — the function that handles all the mandated vfs changes when you go and modify a file 🫶

---

🦋 SYNOPSIS 🦋

int kiocb_modified (struct kiocb *iocb );

---

🎀 ARGUMENTS 🎀

• iocb — the iocb that was modified. that's it. that's the whole argument. she's lowkey the main character here 👑

---

⭐ DESCRIPTION ⭐

so when a file has been modified, this function makes sure that two things happen: the special file privileges get removed, and the time settings get updated. no cap, that's the whole job — cleanup after the glow-up 💅

---

🔥 CONTEXT 🔥

real talk: the caller must hold the file's inode lock. not optional. do not skip this, i'm literally begging 🙈

---

💜 RETURN 💜

• 0 on success ✨
• negative errno on failure 😭
