After the patches were acked, there were still review comments on variable renames etc, which were all addressed. The patches had been under review for more than 8 months with very slow progress.

I would assume that you can also add your changes on top. To make contribution easier, isn't it better to accept at least this patch set (as you acked earlier) and then you can continue working on the improvements?
