Some of these engineers are motivated purely by personal interest, some work for Linux companies, some work for hardware manufacturers, and some are involved with in-house development projects.But all face a common problem:The learning curve for the kernel is getting longer and steeper.The system is becoming increasingly complex, and it is very large. And as the years pass, the current members of the kernel development team gain deeper and broader knowledge of the kernel’s internals, which widens the gap between them and newcomers.I believe that this declining accessibility of the Linux source base is already a problem for the quality of the kernel, and it will become more serious over time.Those who care for Linux clearly have an interest in increasing the number of developers who can con- tribute to the kernel.One approach to this problem is to keep the code clean: sensible interfaces, consistent layout,“do one thing, do it well,” and so on.This is Linus Torvalds’ solution.
