Ugh, looking more at the patch, I'm getting more and more convinces that it is pure and utter garbage. It does "sync_mm_rss(mm);" in mmput(), _after_ it has done the possibly final mmdrop(). WTF? This is crap, guys. Seriously. Stop playing russian rulette with this code. I think we need to revert *all* of the crazy rss games, unless Konstantin can show us some truly obviously correct fix. Sadly, I merged and pushed out the crap before I had rebooted and noticed this problem, so now it's in the wild. Can somebody please take a look at this asap?
You've somehow merged the wrong patch. The correct version can be found here: http://marc.info/?l=linux-kernel&m=133848759505805 -- Markus
