So you are saying that the patch fixes this issue. Do I understand you corretly? And you do not see any other negative side effectes with it applied? I am sorry I didn't have much time to think about feedback from Johannes yet. A more robust throttling method is surely due but also not trivial. So I am not sure how to proceed. It is true that your last test case with only 10 processes fighting resembles the reality much better than hundreds (AFAIR) that you were using previously. Rik, Johannes what do you think? Should we go with the simpler approach for now and think of a better plan longterm? -- Michal Hocko SUSE Labs -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
