  The commit-graph learned to use corrected commit dates instead of
  the generation number to help topological revision traversal.

  How ready is this?

I am reviewing this patch series; it looks good, in a few places 
explanation in the commit message needs improvement.

I think we could in patch 07/10 get a better performance for GDOV 
(overflow chunk for generation numbers) writing with an alternate 
approach, but that might wait for subsequent patch series.

Best,
