I don't really care to much about the implementation inside fs/direct-io.c
(at least for now - once I see it I might still scream "bloody
murder!").

The point is to pass the iov_iter all the way down to a common entry
point in fs/direct-io.c, so that the filesystems don't have to care
for that difference.
