If arg1 is a userland pointer to a structure, then your copyin just
copied in the first four bytes of that structure. And your tracemem is
trying to use those first four bytes as though they were a kernel
pointer. That's not going to work.
You might want this:
this->ptr = copyin(arg1, 10);
tracemem(this->ptr, 10);
