I ask as It would be > nice to have DTrace on FreeBSD by default. 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.
