    Unfortunately, I have no knowledge your program have what assumption
    of file modify. When I reviewed mincore patch from you, you said you
    assume any file are preserved. And If nobody change the files, why do
    we need to care file locks? I have no knowledge a grand picture of
    your design at all.
