For the verifier change in may_access_direct_pkt_data(), would be
great if you could later on follow up with a selftest-suite case,
one where BPF_PROG_TYPE_LWT_IN/OUT prog tries to write and fails,
and one where BPF_PROG_TYPE_LWT_IN/OUT prog uses pkt data to pass
to helpers, for example, so that we can keep testing it when future
changes in that area are made. Thanks.

Good idea, will do.
