It's not smart enough to group changes per module. What I see is that the subject prefix often is based on personal preference of the subsystem maintainer, so far I don't see a rule. Therefore splitpatch seems to use the longest common part of file path's of grouped patches. I'd appreciate hints on maybe better tools for creating patches for tree-wide changes. If possible I'd like to avoid having to manually split and adjust the patches.
