[PATCH -v2 next 0/4] Some cleanup for memcg

[Chen Ridong]

From: Chen Ridong <chenridong@xxxxxxxxxx>

Some cleanup for memcg.

---
v1->v2:
 - drop the patch 'simplify the mem_cgroup_update_lru_size function'.
 - for patch 3, rename '__refill_obj_stock' to replace_stock_objcg, and
   keep the 'objcg equal' check in the calling functions.

Chen Ridong (4):
  memcg: use OFP_PEAK_UNSET instead of -1
  memcg: call the free function when allocation of pn fails
  memcg: factor out the replace_stock_objcg function
  memcg: factor out stat(event)/stat_local(event_local) reading
    functions
