Dumping Large Binary Buffer Through Sysctl

[David Christensen]

I'm looking for a way to dump a large binary debug buffer 
in a driver to a file.  I've currently implemented this
with SYSCTL_ADD_OPAQUE() and it works fine but running the
"sysctl -a" command causes this buffer to be dumped which
is something of a pain.  Is there a better way to do this?
