* Michael Schlueter (michael@duck.syd.de) did the basic structure of the VFS

* Michael Marte (marte@informatik.uni-muenchen.de) did the sound queue,
* /dev/mixer, /dev/sndstat and complemented the VFS interface. He would like
* to thank:
* - Michael Schlueter for initial ideas and documentation on the MFP and
* the DMA sound hardware.
* - Therapy? for their CD 'Troublegum' which really made me rock.
*
* /dev/sndstat is based on code by Hannu Savolainen, the author of the
* VoxWare family of drivers.
