Seems a better approach. I'll redo the patches, but I'm not sure how to
proceed now, since it depends on your change. Patches 4-6 that I did
needs to be dropped/redone. At first my patches 0001/0002 could be
applied with yours, then I would submit another series for the rest. Or
I could take your change and submit your patch along with my series.
