SubjectRe: [PATCH v3] resource: Merge resources on a node when hot-adding memory

Yes and that is hard wired to the memory hotplug code. It is not easy to
make it work outside of section units restriction. So whatever your
memtrace is doing and if it relies on subsection hotplug it cannot
possibly work with the current code.

I didn't get to review your patch but if it is only needed for an
unmerged code I would rather incline to not merge it unless it is a
clear win to the resource subsystem. A report from Oscar shows that this
is not the case though.
