Subject: [PATCH 0/4] thp: simplify freeze_page() and unfreeze_page()
Date: Wed,  3 Feb 2016 18:14:15 +0300	[thread overview]
Message-ID: <1454512459-94334-1-git-send-email-kirill.shutemov@linux.intel.com> (raw)

This patchset rewrites freeze_page() and unfreeze_page() using try_to_unmap()
and remove_migration_ptes(). Result is much simplier, but somewhat slower.
See the last patch for details.

I did quick sanity check. More testing is required.

Any comments?

Kirill A. Shutemov (4):
  rmap: introduce rmap_walk_locked()
  rmap: extend try_to_unmap() to be usable by split_huge_page()
  mm: make remove_migration_ptes() beyond mm/migration.c
  thp: rewrite freeze_page()/unfreeze_page() with generic rmap walkers
