Hmmm, it is my understanding that seq_file is currently not available
for configfs.  Also, we never going to expect these particular calls to
return anything close to PAGE_SIZE, so I am not sure how much of an
issue this really is.

Hmmm, this was some legacy informational code that no longer has a
reason to be seperate.  I will get this merged into a single function.

<nod>  This code current expects the the incoming buffer to be in the
form of 'key0=value0,key1=value1,key2=value2' etc.   Assuming that
parser.h code can handle the comma seperated values, I will look at
getting these converted as well.
