limit not only a factor for global memory pressure, but for
hierarchical reclaim in general, to prefer child memcgs during reclaim
that are in excess of their soft limit.
Because this means prioritizing memcgs over one another, rather than
having explicit soft limit reclaim runs, there is no natural counter
for pages reclaimed due to the soft limit anymore.
Thus, for the patch that introduces this counter:

This patch is fixing a typo of the stats being integrated into mmotm. Does it make sense to fix the
existing stats first while we are discussing other approaches?
