[Devel] [PATCH v13 00/16] kmemcg shrinkers

[Glauber Costa]

> Please note that in contrast to previous versions this patch-set implements
> slab shrinking only when we hit the user memory limit so that kmem allocations
> will still fail if we are below the user memory limit, but close to the kmem
> limit. This is, because the implementation of kmem-only reclaim was rather
> incomplete - we had to fail GFP_NOFS allocations since everything we could
> reclaim was only FS data. I will try to improve this and send in a separate
> patch-set, but currently it is only worthwhile setting the kmem limit to be

> reclaim.

That is unfortunate, but it makes sense as a first step.
