I'm not entirely sure what the question is. For development, you could
base your series on a final release, e.g. 4.9. For reviews and
especially if you are targeting a certain merging window, it's useful to
rebase your patches on a fairly recent -rc, e.g. 4.10-rc3. I would
entirely skip any non-tagged kernel states (like middle of the merging
window) or out of tree branches. There may be a case to rebase on some
other developer's branch but only if there is a dependency that can't be
avoided and usually with prior agreement from both the respective
developer (as not to rebase the branch) and the involved maintainers.
