    Patch from Badari Pulavarty <pbadari@us.ibm.com> and myself
    
    This patch adds the infrastructure for performing asynchronous (AIO) blockdev
    direct-IO.
    
    - Adds generic_file_aio_write_nolock() and make other
      generic_file_*_write() to use it.
    
    - Modify generic_file_direct_IO() and ->direct_IO() functions to take
      "kiocb *" instead of "file *".
    
    - Renames generic_direct_IO() to blockdev_direct_IO().
    
    - Move generic_file_direct_IO() to mm/filemap.c (it is not
      blockdev-specific, whereas the rest of fs/direct-io.c is).
    
    - Add AIO read/write support to the raw driver.
