<p>With the advent of DTrace we are able to replace many of
the internal kernel debugging options, such as TCPDEBUG,
with statically defined tracepoints (SDTs). Tracepoints have now
been added to the system that replicate the functionality of the
TCPDEBUG kernel option. No new kernel options need to be added
&mdash; they are standard with any kernel that has DTrace, which
is included in the default GENERIC kernels in 10.x and HEAD.
