Hi Paul,
I have a few comments on Chapter 9.
1st one is on the description of Figure 9.5.
When one reads the following,
> The ``ideal'' trace was generated by running the sequential code
> shown in Figure 9.2.
one might wonder, "Wait, why a sequential code scales with the number
of CPUs (threads)?"
Of course, route_lookup() of Figure 9.2 can be run concurrently on
multiple CPUs. But it might not be obvious for a novice reader.
Maybe you can make this as a Quick Quiz.
2nd one is for Figure 9.33.
Here, RCU QSBR (quiescent-state-based-reclamation) is mentioned.
However, there seems to be no explanation of what actually it is.
Do you plan to add some explanation or reference?
Thanks, Akira
