What's the overlap, if any, with the current memory limits controlled by 
`memory.limit_in_bytes` and the above `memory.dirty_limit_in_bytes`? If 
I want to fairly balance memory between two cgroups be one a dirty page 
antagonist (dd) and the other an anonymous page (memcache), do I just 
set `memory.limit_in_bytes`? Does this patch simply provide a more 
granular level of control of the dirty limits?


Thanks,

Mike
