Doesn't belong here, this goes in the change log.
My mistake.

Your email client also ate the leading spaces :(
My email client is hotmail. I have come to realize how much hotmail sucks
for email. It eats the leading spaces, converts tabs to spaces, and line
wraps. I will work on getting a new mail account.

What does the 6 and 99 come from? Aren't these #defined in a header file
somewhere?
Good question. The answer is I have no idea. I booted Fedora Core and I
did a ls -l /dev and wrote down the specs for lp0 and parport0. lp0 looked
like crw-rw---- root lp 6, 0 date lp0 so that is what I used. After
reading Linux Device Drivers I found out that 6 is the major number and 0 is
the minor number. The goal was to make sure that the nodes generated by my
patch were the same as the nodes generated before my patch so I used those
numbers. Should I have used different major numbers?
Thanks,
Jason
