Do programmers have to study the Linux kernel source code?

If you want to learn the program, you have to study the Linux kernel source code-general Linux technology-Linux technology and application information. The following is a detailed description. The operating system is something that every programmer must understand. The more the operating system is, the better it is. But should everyone study the Linux kernel source code?

I think that unless you are doing kernel development or kernel porting, the knowledge of kernel code becomes your business knowledge. You don't have to spend too much time researching this. People who know the kernel do not need to be too arrogant. Others may know more about the network than you do. Everyone has their own business and direction. Try to learn it well and learn the language required by the business, even if there is only one language. You are a cool man.
