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
