Unfortunately, I do have that on my phone. See the attachment if
those who might be interested.
Rik, Johannes and myself were discussing how to make the soft_limit
reclaim being smart on picking memcg, the same logic we currently use
to do get_scan_count() between file/anon lru.
After the ground work in this patch is done, I do plan to make that
happen. But for now, I like to focus on the ground work as starting
point.
