SubjectRe: [PATCH V3] nommu: add anonymous page memcg accounting
* Steven J. Magnani <steve@digidescorp.com> [2010-10-21 07:28:08]:

> Add the necessary calls to track VM anonymous page usage (only).
>
> V3 changes:
> * Use vma->vm_mm instead of current->mm when charging pages, for clarity
> * Document that reclaim is not possible with only anonymous page accounting
> so the OOM-killer is invoked when a limit is exceeded
> * Add TODO to implement file cache (reclaim) support or optimize away
> page_cgroup->lru
>
> V2 changes:
> * Added update of memory cgroup documentation
> * Clarify use of 'file' to distinguish anonymous mappings
>
> Signed-off-by: Steven J. Magnani <steve@digidescorp.com>

Acked-by: Balbir Singh <balbir@linux.vnet.ibm.com>

BTW, I have no way of testing this, we need to rely on the NOMMU
community to test this.

Three Cheers,
