Currently, there is no immediate solution. You need to troubleshoot it yourself or provide the device to me for further investigation.

KPM_NAME("kpm-hello-demo");
KPM_VERSION("1.0.0");
KPM_LICENSE("GPL v2");
KPM_AUTHOR("bmax121");
KPM_DESCRIPTION("KernelPatch Module Example");

static long hello_init(const char *args, const char *event, void *__user reserved)
{
pr_info("kpm hello init, event: %s, args: %s\n", event, args);
pr_info("kernelpatch version: %x\n", kpver);
return 0;
}

static long hello_control0(const char *args, char *__user out_msg, int outlen)
{
pr_info("kpm hello control0, args: %s\n", args);
char echo[64] = "echo: ";
strncat(echo, args, 48);
compat_copy_to_user(out_msg, echo, sizeof(echo));
return 0;
}

static long hello_control1(void a1, void a2, void a3)
{
/char str = (char)kp_malloc(sizeof(char) * 10);
kp_free(str);/
int arr = kp_malloc(sizeof(int) * 10);
kp_free(arr);
pr_info("kpm hello control1, a1: %llx, a2: %llx, a3: %llx\n", a1, a2, a3);
return 0;
}

static long hello_exit(void *__user reserved)
{
pr_info("kpm hello exit\n");
return 0;
}

KPM_INIT(hello_init);
KPM_CTL0(hello_control0);
KPM_CTL1(hello_control1);
KPM_EXIT(hello_exit);

只是加了这段，模块就无法加载了
/char str = (char*)kp_malloc(sizeof(char) * 10);
kp_free(str);/
int arr = kp_malloc(sizeof(int) * 10);
kp_free(arr);
请问这个是什么原因呢？
