[RFC Patch 0/2] selftests/mm: assert rmap behave as expected

[Wei Yang <richard.weiyang@gmail.com>]

As David suggested, currently we don't have a high level test case to
verify the behavior of rmap. This patch set introduce the verification 
on rmap by migration.

Patch 1 is a preparation to move ksm related operation into vm_util.
Patch 2 is the new test case.

Currently it covers following four scenarios:

  * anonymous page
  * shmem page
  * pagecache page
  * ksm page

Wei Yang (2):
  selftests/mm: put general ksm operation into vm_util
  selftests/mm: assert rmap behave as expected
