Understanding FUSE: Architecture and Implementation Details

FUSE implements a user‑space file‑system framework where a kernel module creates the /dev/fuse device and forwards VFS requests into kernel queues, while a multi‑threaded daemon reads these requests, optionally uses splice for zero‑copy, processes them, and writes replies back, enabling simple file‑system development without kernel recompilation.
