Because of merge commits the number of which is below 100?

Exactly to avoid Linus' tree being polluted by the extra merge commits. My workflow is really simple -- development happens in (a lot of) topic branches, and each and every time any of the topic branches is updated by a new commit, that topic branch gets merged into for-next. Once code should go to Linus, the branches are merged at once into 'for-linus' brach, and it's guaranteed to be code-wise the same as what was gradually appearing in for-next. What other workflow do you suggest for maintainers like me, who are using a lot of topic branches? If this is so bothering for you, I'd just start instructing for-next downstreams to stop using that branch so that it could be easily rebased.
