That's not really a good idea :( > Not sure why sarcasm is required here - simply pointing out the problem would have been sufficient. These patches were committed by Suzuki who co-maintains the subsystem with me. The committer information likely got transferred when I cherry-picked the patches when putting the pull request together. > thanks, > > greg k-h

Is this tree/branch in linux-next now? If so, you should have gotten an email. My scripts were sent to the workflow mailing list a year or so ago, I can dig them up if needed. thanks, greg k-h
