You'll reasonably often see in the kernel: - a patch-series by Andrew (where nothing but filename clustering really would help: the committer is me, and the thing is linear) - linearly on top of that, a git merge that was a fast-forward (especially from the subset of people who actively rebase their trees: that notably includes Dave Miller, but also for example the DVB people) so purely a first-parent logic would not catch that case at all (but the committer would at least catch the "patch-series by Andrew" -> "Merge of network tree by Davem" break). But especially with long patch-series through Andrew, it would be nice to have some other heuristics (although they _tend_ to be fairly random, especially at the end of the release cycle - at the beginning, I tend to have series of 100-200 patches that often _could_ be clearly clustered into a few clusters). Anyway, the real win of clusterign would likely be for big releases, ie soemthing like "v2.6.18..v2.6.19-rc1", where there's definitely some clustering even apart from just merging (although the merge topology will definitely get some of it)
