    it should work, but maybe some performance loses if the
    cluster size is not page-alignment, for example, 4 sector/cluster
    in a 4KB/page system.
    because it will fall back to the block_read_full_page when
    non-adjacent block found in do_mpage_readpage, i think.
    the same applies to mpage_readpages too.

    thanks.
