Hello Peter, Patch 1 implements the cpu.pressure fix for cgroups we were looking at recently, 2 is the cgroup hierarchy walk optimization you proposed. Patch 3 adds a MAINTAINER entry for psi, as at least one person tried looking for it and couldn't find it. If they look alright to you, it'd be great to get them into 5.7. Based on 5.6-rc6.
