You received comments already that you need to base your work on recent
Linux kernel and use scripts/get_maintainers.pl to notify necessary
parties. 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,
