Excellent -- I'm really glad to see this getting sorted out at last. I think there's a reasonable argument that we should be compiling options KDTRACE_HOOKS into GENERIC, and likewise enabling CTF on the kernel by default in 9.x. Part of the point of DTrace is that it "just works", and we already compile CDDL modules by default (and the hooks don't affect the license of the base kernel as far as I'm aware). Any thoughts on this? Robert
