fscrypt_drop_inode(9)

💖 NAME 💖

okay bestie, this is fscrypt_drop_inode(9), straight from the Kernel API Manual — and it’s literally here to check whether the inode’s master key has been removed.

• fscrypt_drop_inode — check whether the inode’s master key has been removed.

---

✨ SYNOPSIS ✨

okay so the signature is exactly this, no edits, no cap:

int fscrypt_drop_inode (struct inode *inode );

---

🎀 ARGUMENTS 🎀

• inode — an inode being considered for eviction. yes, that’s the whole vibe 🫶

---

🌸 DESCRIPTION 🌸

Filesystems that support fscrypt must call this from their ->drop_inode method, so that encrypted inodes get evicted as soon as they’re no longer in use and their master key has been removed. it’s giving “clean up your room before you leave,” but for inodes 💅

---

🦋 RETURN 🦋

1 if fscrypt wants the inode to be evicted now, otherwise 0. so 1 is the “go off, leave the chat” signal, and 0 is “nah, stay a lil longer” ✨
