[PATCH 2/7] sysctl: parport remove binary paths.

Eric W. Biederman
2007-08-10T21:02:18Z

The sysctl binary paths don't look as if they even code work,
.data is not filled in, and all of the proc_handlers look at
extra1 and there is not strategy routine.

So just kill the binary paths.

In addition this patch removes the setting of extra1
on directories. It doesn't look like the parport code
ever examines it, and it's bad sysctl form.
