Message

Many workloads consumes significant amount of memory in pagetables. One
specific use-case is the user space network driver which mmaps the
application memory to provide zero copy transfer. This driver can
consume a large amount memory in page tables. This patch series exposes
the pagetable comsumption for each memory cgroup.
