[v1 0/3] Support memory cgroup hotplug

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In the absence of hotplug we use extra memory proportional to
(possible_nodes - online_nodes) * number_of_cgroups. PPC64 has a patch
to disable large consumption with large number of cgroups. This patch
adds hotplug support to memory cgroups and reverts the commit that
limited possible nodes to online nodes.

I've tested this patches under a VM with two nodes and movable
nodes enabled. I've offlined nodes and checked that the system
and cgroups with tasks deep in the hierarchy continue to work
fine.

Balbir Singh (3):
  Add basic infrastructure for memcg hotplug support
  Move from all possible nodes to online nodes
  powerpc: fix node_possible_map limitations
