> memory.numa_migrate migrates asynchronously, so it skips the folios that
> are under writeback or locked for it when it gets to them. The
> inactive_disk_file variant dirties 1 GiB of a disk file with write
> faults, and writeback of that file is still running when the test
> migrates it, so part of the file can stay on the source node.

> Populate that file with read faults instead. The file is a hole, so its
> page cache stays clean and nothing is written back. disk_file keeps
> writing to its pages while they are migrated and is left as is.
