    [PATCH] CDROMREADAUDIO dma support · f644f166
    Jens Axboe authored
    This small patch builds on top of the blk_rq_map_user() patch just sent,
    and enables us to easily support DMA for CDROMREADAUDIO cdda extraction.
    It's quite amazing how much cool stuff you can with the new block layer
    :-)
    
    Patch has intelligent fall back from multi frame dma to single frame
    dma, and further to old-style pio ripping in case of hardware problems.
