Thanks, i explained the reason during my last reply.
Andrew has already picked this patch to -mm tree.

Just because it's in Andrews tree doesn't mean it will end up upstream. ;)

Anyhow, no really strong opinion, it's simply unnecessary code churn 
that makes bisecting harder without real value IMHO.

I think it's a good change - mem_sections refers to multiple instances
of a mem_section.  Churn is a pain, but that's the price we pay for more
readable code.  And for having screwed it up originally ;)
