Re: [RFC PATCH] cgroup: introduce proportional protection on memcg

[Chris Down]

I'm confused by the aims of this patch. We already have proportional reclaim 
for memory.min and memory.low, and memory.high is already "proportional" by its 
nature to drive memory back down behind the configured threshold.

Could you please be more clear about what you're trying to achieve and in what 
way the existing proportional reclaim mechanisms are insufficient for you?
