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 + — they are standard with any kernel that has DTrace, which + is included in the default GENERIC kernels in 10.x and HEAD. +
