Hi Andrea!

No useful comments on the statm reporting issue.

Yes, we've got reports of bad OOM killing behaviour (is that what you're
talking about?) 

One thing is the removal of "if (nr_swap_pages > 0) goto out" from oom_kill() 
causes problems (spurious oom kill). 

We need to throttle more, on page reclaiming progress I think.

Take a look at

What else you're seeing?

Nick has been working on that lately I think. What is the problem?
