From: "Kirill A. Shutemov" <redacted>

Hi Jiri,

Sorry for late answer. It took time to reproduce and debug the issue.

Could you test two patches below by thread. I expect it to fix both
issues: put_huge_zero_page() and Bad rss-counter state.

Kirill A. Shutemov (2):
  thp: fix anononymous page accounting in fallback path for COW of HZP
  thp: avoid race on multiple parallel page faults to the same page
