So imagining for an instant we apply this patch, and this patch only. The behavior we get is that when memcg gets pressure, it will shrink globally, but it will at least shrink anything. It is needless to say this is not enough. But I wonder if this isn't better than no shrinking at all ? Maybe this could be put ontop of the slab series and be the temporary default while we sort out the whole shrinkers problem? -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
