memcg: slab control

[David Rientjes <rientjes@google.com>]

Hi,

I wanted to see what the current ideas are concerning kernel memory 
accounting as it relates to the memory controller.  Eventually we'll want 
the ability to restrict cgroups to a hard slab limit.  That'll require 
accounting to map slab allocations back to user tasks so that we can 
enforce a policy based on the cgroup's aggregated slab usage similiar to 
how the memory controller currently does for user memory.

Is this currently being thought about within the memcg community?  We'd 
like to start a discussion and get everybody's requirements and interests 
on the table and then become actively involved in the development of such 
a feature.

Thanks.
