Are you saying that the original bug report may not actually be a problem? Is ms->rss actually protected in _all_ of the right places, but people got confused because of the syntactic sugar?
I don't know if all of them are ok, most are.
Someone would need to do the analysis. David's patch could be used as a good starting point. A quick glance at mm/memory.c shows these spots need to be fixed:
1) End of zap_page_range() 2) Middle of do_swap_page 3) do_anonymous_page 4) do_no_page
