If DTRACE is enabled at compile time, all kernel breakpoint traps are first given to dtrace to see if they are triggered by a FBT probe. Previously if dtrace didn't recognize the trap, it was silently ignored breaking the handling of other kernel breakpoint traps such as the debug.kdb.enter sysctl. This only returns early from the trap handler if dtrace recognizes the trap and handles it.
