I don't see having the time to review this set before the middle/end of next
week.  I also understand we are crunched by time if we want to get this in
for the upcoming merge window.

If memory serves me well there wasn't anything controversial about this work.
Under normal circumstances I'd give it a final look but I trust Suman to have
carried out what we agreed on.

Bjorn - if you are happy with this set then go ahead and queue it.

Thanks,
Mathieu
