This looks like a technique for writing to any old file system from inside the
kernel.  What about the other direction.  Do you have to set up a kernel thread 
per
data stream and use a similar technique to "read" from the file system?  Or 
maybe one
could concoct an inside-the-kernel kludge to use poll().
