Yeah, I maintain *.v branches around. Each time I need to send a new version of a patchset I do: git checkout -b base.branch.v base.branch and then continue working on git checkout base.branch for the new version. :) I try to make sure to only push base.branch to git.kernel.org once I know it builds fine. Before that I only push to other code-hosting platforms. One of the reasons being that I try to avoid upsetting the various build bots. :)
