The body describes the mechanics of both test cases, but does not state
why this new test is needed -- what gap does it fill? Does connect01 or
connect02 already cover AF_UNIX-specific error paths?

Rule 2 in the LTP commit-message guidelines requires the body to state
the motivation or problem being solved, not just what was changed.
A sentence like "connect01/02 only cover generic socket error paths and
do not test AF_UNIX-specific errors" would satisfy this.
