reclaim memory from cgrouped app(/kernel)

[Еньшин Андрей <and.enshin@xxxxxxxxx>]

Hi,

does kernel reclaim memory inside cgroup - from apps running inside
cgroup and from part of kernel taking memory somehow related to this
cgroup - if there is no overall memory pressure in system but memory
usage in this particular cgroup is close to limit?

If yes, will kernel reclaim pages marked as MADV_FREE?
