Might be. But historically fuse had this behavior and I'd be very reluctant to change that unconditionally. With a systemwide maximal timeout for fuse requests it might make sense to allow sync(2), etc. to wait for fuse writeback. Without a timeout allowing fuse servers to block sync(2) indefinitely seems rather risky. Thanks, Miklos
