[PATCH V2 0/2] memcg:add the soft_limit reclaim in global direct reclaim

[Ying Han <yinghan@google.com>]

We recently added the change in global background reclaim which counts the
return value of soft_limit reclaim. Now this patch adds the similar logic
on global direct reclaim.

We should skip scanning global LRU on shrink_zone if soft_limit reclaim does
enough work. This is the first step where we start with counting the nr_scanned
and nr_reclaimed from soft_limit reclaim into global scan_control.

The patch is based on mmotm-2011-04-14-15-08 plus
0001-check-pageunevictable-in-lru_deactivate_fn.patch from Minchan.

Ying Han (2):
  Add the soft_limit reclaim in global direct reclaim.
  Add stats to monitor soft_limit reclaim
