Subject: [PATCH v2 0/2] KSM: support smart-scan feature
Date: Fri,  1 Dec 2023 13:09:28 -0800	[thread overview]
Message-ID: <20231201210930.2651725-1-shr@devkernel.io> (raw)

This patch series makes two changes:
- Disable the smart-scan feature for ksm01 - ksm04
  This is necessary to make sure that the volatile metrics have the
  expected counts.
- Add a new test for the smart-scan feature
  The new test verifies that the smart-scan feature skips pages when it has
  been enabled for a VMA.

Versions:
- V2:
  - Disable smart_scan in the test setup structure
  - Remove the changes in create_same_memory()
  - Add the new testcase ksm07 for the smart scan test
  

Stefan Roesch (2):
  mem: disable KSM smart scan for ksm tests
  add ksm test for smart-scan feature
