More thoughts about this issue. I think the problem is in the
read_hook. If we're just reading, it make no difference whether it's
from journal or real location, however, if the read_hook is not empty,
we also need to pass the sector location to upper layer. Perhaps we
can disable journal when the read hook is not null ?
