It is much more preferable to come up with a systematic solution rather than a pile of workarounds. Pushing workarounds just because they are easy to backport to distribution kernels is a wrong criteria. The current OOM killer code is far from ideal. Some of the heuristics might be suboptimal or even outright wrong. But piling more on them is not a way forward. -- Michal Hocko SUSE Labs -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
