When your Linux computer starts, a virtual file system proc is created. This file system disappears after you shut down the computer. Linux Kernel information is stored in the /proc/version file, which is used by Linux at runtime. Use the cat command line utility to print version information...

查阅资料后,我发现 /proc/stat 的内容是由 fs/proc/stat.c 中的 show_stat 函数提供的。在文件底部,你可以看到它调用了 proc_create,将“stat”设置为 /proc 中的一个文件。总之,show_stat 调用 get_idle_time,而后者又调用了 get_cpu_idle_time_us。最后一个函数非常有意思,因为它上方的注释提到:“这个...
