ecryptfs_d_revalidate(9)

💅 ecryptfs_d_revalidate(9) 💅

okay so this is a page from the Kernel API Manual, bestie — like the actual kernel docs, not the vibes-only version. buckle up 🎀

---

✨ NAME ✨

ecryptfs_d_revalidate — revalidate an ecryptfs dentry, that's the whole gig 🦋

---

✨ SYNOPSIS ✨

int ecryptfs_d_revalidate (struct inode *dir , const struct qstr *name ,
       struct dentry *dentry , unsigned int flags );

like yes she takes four args and returns an int, we been knew 💅

---

✨ ARGUMENTS ✨

• dir — the inode of the expected parent. the parent, the one you expect, okay 👑
• name — the expected name. yep, the name you're expecting, not a surprise 🎀
• dentry — the dentry to revalidate. she's the main character of this function fr fr 🦋
• flags — lookup flags. the flags for the lookup. that's it, that's the whole thing 🌸

---

✨ DESCRIPTION ✨

so this bad boy gets called when the VFS needs to revalidate a dentry. and it's not a one-time thing either — it's literally called whenever a name lookup finds a dentry in the dcache. every time, bestie 😭

and here's the thing: most filesystems leave this as NULL, because all their dentries in the dcache are valid already. so they just don't bother. iconic of them honestly. but not ecryptfs — ecryptfs said "not me, I'm built different" and wrote a whole function 💀

returns 1 if it's valid, 0 otherwise. that's the contract. no in-between, no "well actually", just 1 or 0. vibe check: pass or fail ⭐
