Hi Chao Gao,

I've left a few comments on your patches. It looks like the structure of 
your patch set has been shifting between postings. I’d recommend 
reviewing the build-up of changes more carefully — see my reply on patch3.

Additionally, your approach to the ongoing discussion comes across as 
somewhat reserved. Since you’re presenting a counterpoint to the 
maintainer’s suggestion, I’d encourage you to articulate your reasoning 
more clearly (see my comment on patch 7).

Most of other feedback focuses on refining individual changes. 
Specifically, your upcoming modifications to the initialization sequence 
do not look super clear. My suggestions in patch 4 reflect my 
interpretation, but please consider whether there's a clearer way to 
present the new configuration settings.

Thanks,
Chang
