💅 sgx_encl_put_backing — a Kernel API Manual moment

okay bestie, so you've wandered into the Kernel API Manual (yes, that's the manual name, we love a formal moment) and the function we're obsessing over is literally called sgx_encl_put_backing. Say it with me. Slay.

✨ NAME ✨

sgx_encl_put_backing — unpin the backing storage 🫶

That's it. That's the whole vibe. It puts the backing storage back. Unpins it. Releases it from its little pin jail. Iconic behaviour tbh.

---

🌸 SYNOPSIS 🌸

void sgx_encl_put_backing(struct sgx_backing *backing);

Note the void — no return value, no dramatic exit status, she simply does the thing and leaves. Main character energy. 💅

🎀 ARGUMENTS 🎀

• backing — data for accessing backing storage for the page. That's the struct you hand over so she knows which backing storage we're unpinning. No backing, no unpinning. Them's the rules. 🦋
