The driver implementation part is clear.
But the paths of several header files really confuse me. the Linux 2.6.13 file is organized as follows:
The header file is as follows:

Linux Process Scheduling analysis and linux scheduling AnalysisOverview
Multi-process scheduling is essential for the operating system. Some people say that process scheduling is the most important part of the operating system. I think this is an absolute saying, just as many people say that "a function is XX times more efficient than a function", it is out of the actual environment, these conclusions are o
displayed and Linux and an optional initial RAM disk (temporary root file system) are loaded into memory. When the image is loaded, the second stage of the bootloader gives control to the kernel image and the kernel can decompress and initialize it. During this phase, the second stage of the bootloader detects the system hardware, enumerates the system-linked hardware devices, mounts the root device, and then loads the necessary kernel modules. After
