In your harsh replies to critics, obviously.

And what I should get?

$ cat tmp.c
void (*casting_pointers())()
{
    void *void_fn = (void*)casting_pointers;
    void (*fn)() = (void (*)()) void_fn;
    return fn;
}
$ gcc -Wall -c tmp.c

I don't know what warnings of MSVC you are talking about, but assuming you are right with it and MSVC warnings are useless, you should use gcc -Wall and its warnings or some external static code analizer to check your code.

I bet you are doing it wrong. I have no idea what definitions of ksm and vcpu structs are (I'm too lazy to do such a research), but look:

    uintptr_t k = (uintptr_t)container_of(vcpu, struct ksm, vcpu_list);

I'm sure that warnings come from inside of container_of due to wrong type of vcpu. To compile this without warnings struct ksm needs be something like:

        struct ksm {
                ...
                struct vcpu vcpu_list;
                ...
        };

I suggest that vcpu_list declared as a struct list_head, therefore you are getting those warnings. Clean your code and either make an explicit cast of vcpu to struct list_head*, or change type of an arg in function declaration to reflect the type of field in struct ksm.

> Also the incompatible pointer warning that was _only_ ignored for just 1 function...

If it is true, than I understand your behaviour even less. Why you need to speak about MSVC and your hatred of compiler warnings, instead of clear explanation of the issue? One unresolved warning is not so bad as systematically ignored warnings. Acting such a way you are showing youself as ignorant fool.
