While I don't agree with what you are saying above, I appreciate that you will try
to be patient. Not every review can be outright helpful, sometimes they are just
pointers to something the reviewer prefers/likes and it's ok to ignore them.
The best thing to do with an unhelpful review is to just set it aside.

I didn't start out reviewing by thinking that I will pull out all tiny places
where words are misspelled or structures have a typedef. I noticed
the typedef usage while replying to you and thought of mentioning it. It's right there in
the same patch, not across different patches and I probably would have posted a patch
myself.

Anyway, I will make another attempt based on your input that we should focus on the design
aspect.

Thanks,
Bandan
