Hi Kamezawa-san, > I'm now writing remove-lock-page-cgroup patches. it works well. > please wait for a while... I'm looking forward to those patches. By the way, I'm glad if memory-cgroup has a feature which can make a page_cgroup move between cgroups with small overhead. It makes bio-cgroup improve the accuracy of tracking down pages.
