Linux kernel statistics from the other perspective than existing ones

[Satoru Takeuchi]

I wrote an article about linux kernel statistics by analyzing linux kernel
source code. Although there are many such the articles, most of them mainly
focus on who develops linux kernel. However, this article doesn't care about
that at all. It focuses on the following things instead.

- Which subsystems the kernel consists of?
- Which type of drivers are the main contents in the whole drivers code?
- Whether the newly added drivers code are mainly for new drivers
  or for existing ones?
- What are the characteristics of both rc kernels and stable kernels?

Please take a look at it.
