Subject: [PATCH v2 0/3] vmstats/vmevents flushing

This is v2 of the patchset (v1 has been sent as a set of separate patches).
Kbuild test robot reported build issues:
memcg_flush_percpu_vmstats() and memcg_flush_percpu_vmevents() were
accidentally placed under CONFIG_MEMCG_KMEM, and caused
!CONFIG_MEMCG_KMEM build to fail.

V2 contains a trivial fix: both function were moved out of
the CONFIG_MEMCG_KMEM section.

Also, the add-comments-to-slab-enums-definition patch were merged into
patch 2.

Andrew, can you, please, drop the following 4 patches from the
mm tree and replaces them with this updated version?
  1) mm: memcontrol: flush percpu vmevents before releasing memcg
  2) mm-memcontrol-flush-percpu-slab-vmstats-on-kmem-offlining-fix
  3) mm: memcontrol: flush percpu slab vmstats on kmem offlining
  4) mm: memcontrol: flush percpu vmstats before releasing memcg

Thanks!

  mm: memcontrol: flush percpu vmstats before releasing memcg
  mm: memcontrol: flush percpu slab vmstats on kmem offlining
  mm: memcontrol: flush percpu vmevents before releasing memcg
