Hi Kevin,

For similar case, if the fixed commit has been pulled by main tree, I am
updating the fixes tag on the next-net,
if not pulled yet, mostly I am squashing the fix to the original commit in
next-net, if I can't squash for some reason Thomas is fixing the tag while
merging into the main tree. (Our check-git-log commit detected wrong Fixes tag
already.)

So if you pick fixes from main tree only, the fixes tags will be always correct.
If you pick commits from sub-trees, fixes tag won't be only problem, the commits
also will be not fully tested...
