[Click] Passing information from user level application to Click kernel module

[Eddie Kohler]

Also realize that it is extremely unlikely that passing a filename to the 
kenrel will be useful.  Lots of people seem to want to use fopen() etc. in the 
kernel but you can't.  If you want to access file data and you are not already 
a kernel programmer, then do it at user level.
