使用C语言，编写一个内核1024线程，3s之后，关闭1024内核线程的 内核模块程序

在C语言中编写一个内核模块程序，创建并管理1024个线程，然后在3秒后终止这些线程，需要对Linux内核API有深入理解，并且通常使用的是`pthread_create()`函数来创建线程，`pthread_exit()`或`pthread_join()`来结束线程。由于这涉及到操作系统底层操作，以下是简化版的示例代码：

#include <linux/module.h>
#include <linux/kernel.h>
#include <linux/sched.h>
#include <pthread.h>

#define THREAD_COUNT 1024

static int __init init_module(void) {
    int i;
    pthread_t threads[THREAD_COUNT];

    printk(KERN_INFO "Creating %d threads...\n", THREAD_COUNT);

    for (i = 0; i < THREAD_COUNT; i++) {
        if (pthread_create(&threads[i], NULL, thread_func, NULL)) {
            printk(KERN_ERR "Failed to create thread %d\n", i);
            return -ENODEV;
        }
    }

    // Wait for 3 seconds
    msleep(3 * 1000);

    printk(KERN_INFO "Terminating all threads...\n");

    // Terminate each thread by joining with it
    for (i = 0; i < THREAD_COUNT; i++) {
        if (pthread_join(threads[i], NULL)) {
            printk(KERN_ERR "Failed to join thread %d\n", i);
        }
    }

    printk(KERN_INFO "All threads terminated.\n");
    return 0;
}

static void (*thread_func)(void*) = NULL;

static void thread_func(void* arg) {
    // Your thread function goes here
    // It will run in parallel with other threads
    // Sleep for a while before exiting
    schedule_timeout_uninterruptible(1); // Sleep for a short time
    pthread_exit(NULL);
}

static void __exit cleanup_module(void) {
    printk(KERN_INFO "Cleaning up module...\n");
}

module_init(init_module);
module_exit(cleanup_module);
