    Subjectfile read/write within device driver

    What is the preferred mechanism for doing file I/O from within a
    module?

    A)
    bh = bread( dev, disk_offset, 4096 );

    or...
    B)
    new_bh = kmalloc();
    new_bh->everything = new_stuff;
    make_request( MAJOR(dev), WRITE, new_bh );

    or...
    C)
    something else entirely?

    Thanks!
