How to correctly create and stop kthreads?
Creating and managing kernel threads (kthreads) in the Linux kernel requires knowledge of kernel development. Kernel threads are lightweight threads that run in kernel space, and they should be used with care because improper management can lead to system instability. Below is a basic outline of how to create and stop kthreads in the Linux kernel: **Creating a Kthread:** 1. **Include Required Header Files**: Include the necessary header files in your kernel module code. For kthreads, you'll need to include `linux/kthread.h` and `linux/completion.h`. ```c #include <linux/module.h> #include <linux/kernel.h> #include <linux/kthread.h> #include <linux/completion.h> ``` 2. **Declare Kthread Function**: Declare the function that will run as a kthread. This function should return an `int` and accept a single `void*` argument. ```c static int my_kthread(void *data); ``` 3. **Initialize a `struct task_struct`**: Create a `struct t
