I count a threatened FILIBUSTER as a FILIBUSTER.
A Cloture Vote is the finished product.
I do not limit their obstruction to a floor vote.
Boyle and Haynes fits that bill too, as does Kavanaugh as you noted. I would say that any judge that fails to come up for a vote has been filibustered; becuase that is the only reason for not voting on the nomination.
Myers and Saad were subjected to failed cloture votes in the 108th Congress - and for them you'll get near unanimous agreement that their nominations were openly filibustered.
