Ahh. You're talking about the shrinker interface. Yes, there is no way to
tell if the freed memory will be actually released (and if not, then
yes, we released it unnecessary).
I don't tell about actually released or not.

Just a quick wonder: why would we need to place it into memcg, when we

This commit implements David Rientjes' idea of mempressure cgroup.
The main characteristics are the same to what I've tried to add to vmevent
API; internally, it uses Mel Gorman's idea of scanned/reclaimed ratio for
pressure index calculation. But we don't expose the index to the userland.
