Wei Yang c9615059ca selftests/mm: test that rmap behaves as expected ... As David suggested, currently we don't have a high level test case to verify the behavior of rmap. This patch introduce the verification on rmap by migration. The general idea is if migrate one shared page between processes, this would be reflected in all related processes. Otherwise, we have problem in rmap. Currently it covers following four scenarios: * anonymous page * shmem page * pagecache page * ksm page Link: https://lkml.kernel.org/r/20250819080047.10063-3-richard.weiyang@gmail.com Signed-off-by: Wei Yang <richard.weiyang@gmail.com> Suggested-by: David Hildenbrand <david@redhat.com> Cc: David Hildenbrand <david@redhat.com> Cc: Lorenzo Stoakes <lorenzo.stoakes@oracle.com> Cc: Rik van Riel <riel@surriel.com> Cc: Liam R.
