This patch and the 3 patches before it all look like basic bug
fixes to current code, not really part of the new hybrid topology
feature work.
As such I'd suggest sending these first four patches as a separate
series, so the bug fixes can be merged fairly quickly. I expect the
rest of the hybrid topology series is going to take a long time to
get agreement on, so no need to delay the easy bug fixes.
