evm_metadata_changed(9)

💅 evm_metadata_changed(9) — from the Kernel API Manual, bestie

okay so picture this: you're deep in the <pink>Kernel API Manual</pink> (yes that's the manual name, we're fancy now 🎀) and you stumble on this little icon. Let me tell you everything about it, no gatekeeping, periodt.

✨ NAME ✨

evm_metadata_changed — literally just detects changes to the metadata. That's the whole gig. She's a vibe check for metadata fr fr 🔥

---

🦋 SYNOPSIS 🦋

bool evm_metadata_changed (struct inode *inode , struct inode
*metadata_inode );

like, copy it exactly how it's written, don't come for me about the spacing, that's canon 💀

---

🌸 ARGUMENTS 🌸

• inode — a file's inode. you know, the little main character that represents the file itself 🫶
• metadata_inode — the metadata inode. her whole job is metadata energy 👑

---

💖 DESCRIPTION 💖

Okay so on a <purple>stacked filesystem</purple> (yes, stacked, not a regular one, pay attention bestie ✨) this function detects whether the metadata has changed.

And if that's the case — like, if the metadata did change — it resets the evm_status associated with the inode that represents the file. Boom. That's it. That's the function. Simple, iconic, does exactly what it says on the tin 💅

No cap, that's the entire description. She's efficient.
