The fd in -> open callback is temporary (the files restoring engine will re-open one under some other fd). But since we add this fd to future repair off, this off will fail working on wrong fd. Move scheduling for repair-off into port-open where the corrent fd is known. Signed-off-by: Pavel Emelyanov <xemul@parallels.com>
