✨ fscrypt_set_context(9) ✨

okay bestie, this little icon is from the Kernel API Manual and it's all about setting up the fscrypt context on a shiny new inode 💖

---

🎀 NAME 🎀

fscrypt_set_context — Set the fscrypt context of a new inode

---

🦋 SYNOPSIS 🦋

int fscrypt_set_context (struct inode *inode , void *fs_data );

---

🌸 ARGUMENTS 🌸

• inode — a new inode, periodt ✨
• fs_data — private data given by FS and passed to ->set_context. that's the whole vibe 🫶

---

💅 DESCRIPTION 💅

okay so listen: this should be called after fscrypt_prepare_new_inode, generally during a filesystem transaction. no cap.

Everything here must be GFP_NOFS-safe. like, literally everything — that part is not optional 💀

---

🔥 RETURN 🔥

• 0 — success, yay 🎉
• -errno — failure, sad but valid 😭
