During this time, I read "Linux kernel source code Scenario Analysis" and wrote some insights. Reading the kernel source code is very interesting. It is like a line that concatenates basic computer courses such as operating systems, compilation principles, C language, data structures and algorithms, and computer architecture. I think the kernel source code is usi

Regarding the differences between kernel-devel, kernel-header, and kernel src, A kernel-header package wowould contain 'header files' needed by some applications which wocould be built on the target machine, for example modules used by virtualbox or the proprietary nvidia driver.Http://kernelnewbies.org/KernelHeadersA

Make a brief note in case you forget.The reason we need to synchronize is that we have concurrent access to shared resources. The code snippet that we will access or manipulate the shared resource is called a "critical section", which is called a "race condition" if the two execution threads are executing simultaneously in the same critical section. Here the term execution thread refers to any code instance that is executing, such as a process executed in the
