As far as I remember the issue was that some people (maybe in behalf of
companies) expressed their concern if the GENERIC kernel does not come
with BSD-license-only code. For this reason jb@ worked on the
KDTRACE_HOOKS code. What we need now is a verification, that this part
of DTRACE is not "CDDL-infected". There was an internal discussion,
triggered by the talk you mentioned above. A part (the simple one) of
the code has been reviewed. Anyone interested in getting KDTRACE_HOOKS
enabled by default is free to do an independent review and post it here.

Bye,
Alexander.
