Subject: [PATCH 0/5] memcg: charge page tables (x86) and pipe buffers

Hi,

There are at least two object types left that can be allocated by an
unprivileged process and go uncharged to memcg - pipe buffers and page
tables. This patch set tries to make them accounted.

Comments are welcome.

Thanks,

Vladimir Davydov (5):
  mm: uncharge kmem pages from generic free_page path
  fs: charge pipe buffers to memcg
  memcg: teach uncharge_list to uncharge kmem pages
  mm: add __get_free_kmem_pages helper
  x86: charge page table pages to memcg
