Subject: [PATCH 0/7] thp/khugepaged improvements and CoW semantics
Date: Fri, 27 Mar 2020 20:05:54 +0300	[thread overview]
Message-ID: <20200327170601.18563-1-kirill.shutemov@linux.intel.com> (raw)

The patchset adds khugepaged selftest (anon-THP only for now), expands
cases khugepaged can handle and switches anon-THP copy-on-write handling
to 4k.

Please review and consider applying.

Kirill A. Shutemov (7):
  khugepaged: Add self test
  khugepaged: Do not stop collapse if less than half PTEs are referenced
  khugepaged: Drain LRU add pagevec to get rid of extra pins
  khugepaged: Allow to callapse a page shared across fork
  khugepaged: Allow to collapse PTE-mapped compound pages
  thp: Change CoW semantics for anon-THP
  khugepaged: Introduce 'max_ptes_shared' tunable
