khugepaged: add self test
Patch series "thp/khugepaged improvements and CoW semantics", v4.
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.
This patch (of 8):
The test checks if khugepaged is able to recover huge page where we expect
to do so. It only covers anon-THP for now.
Currently the test shows few failures. They are going to be addressed by
the following patches.
