Subject: [PATCH 0/4] Bugfixes for THP refcounting

Hi,

There's few bugfixes for THP refcounting patchset. It should address most
reported bugs.

I need to track down one more bug: rss-counter mismatch on exit.

Kirill A. Shutemov (4):
  mm: do not crash on PageDoubleMap() for non-head pages
  mm: duplicate rmap reference for hugetlb pages as compound
  thp: fix split vs. unmap race
  mm: prepare page_referenced() and page_idle to new THP refcounting
