"But the fruit of the Spirit is love, joy, peace, forbearance, kindness, goodness, faithfulness, gentleness and self-control. Against such things there is no law." (Gal. 5:22-23)

Does "faithfulness" here mean faith or simply obedience to God's law? Obviously, in many places of the Bible this is the case with the term "faithfulness."

Also, why is not humility/repentance a fruit of the Spirit (at least, according to the text in question)?
