[ text/plain ] This adds two tests for memory page migration. One for normal page migration which works for both 4K or 64K base page size kernel and the other one is for huge page migration which works only on 64K base page sized 16MB huge page implemention at the PMD level.can you also add the test in this commit e66f17ff717 ("mm/hugetlb: take page table lock in follow_huge_pmd()")
Thought about it but thats kind of bit tricky. All self tests have finite runtime. Test case in that commit has two processes which execute for ever and try to create the race condition. We can try to run it for *some time* looking for races instead ?
