This is the fourth patchset and still you did not do it. Maybe there is some misunderstanding or trouble using scripts/get_maintainers.pl, so could you clarify: 1. What is this based on? Output of: git describe 2. What does the scripts/get_maintainers.pl print when you run on this patchset? Best regards, Krzysztof
