I haven't seen above well yet. But A article says that DTrace sounds
like 30,000 lines of debug print. I have written about 50 lines
of debug print in my 4.10-R kernel to chase my umass issue.
If the output of it exists on a trace log file, It may be one of
DTrace feature. I saw the some sort of debug print lines in the
kernel source of 4.10-R. If you enable them and gather the information
to a file, it may be nearly equal DTrace. But I can't warrant or guarantee
you the performance. DTrace may be a kinda elegant debug mode
kernel, I guess.
