[PATCH 0/6] *** memcg: make throttle_vm_writeout() cgroup aware ***

[Greg Thelen <gthelen@google.com>]

This series aims to:
- Make throttle_vm_writeout() cgroup aware.  Prior to this patch, cgroup reclaim
  would consider global dirty limits when deciding to throttle.  Now cgroup
  limits are used if the cgroup being reclaimed has dirty limits.

- Part of making throttle_vm_writeout() cgroup aware involves fixing a negative
  value signaling error in mem_cgroup_page_stat().  Previously,
  mem_cgroup_page_stat() could falsely return a negative value if a per-cpu
  counter sum was negative.  Calling routines considered negative a special
  "cgroup does not have limits" value.

Greg Thelen (6):
  memcg: add mem_cgroup parameter to mem_cgroup_page_stat()
  memcg: pass mem_cgroup to mem_cgroup_dirty_info()
  memcg: make throttle_vm_writeout() memcg aware
  memcg: simplify mem_cgroup_page_stat()
  memcg: simplify mem_cgroup_dirty_info()
  memcg: make mem_cgroup_page_stat() return value unsigned
