Unfortunately,  I do have that on my phone. See the attachment if

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
