[PATCH v1 0/4] Page counters optimizations

[Roman Gushchin]

From: Roman Gushchin <roman.gushchin@xxxxxxxxxxxxx>

This patchset reorganizes page_counter structures which helps to make
memory cgroup and hugetlb cgroup structures smaller (20%-35%) and
more cache-effective. It also eliminates useless tracking of protected
memory usage when it's not needed.
