The earlier commits [0] removed duplicated code from bpf_setsockopt(). This series is to remove duplicated code from bpf_getsockopt(). Unlike the setsockopt() which had already changed to take the sockptr_t argument, the same has not been done to getsockopt(). This is the extra step being done in this series.
