Eryu, These are the two remaining copy_file_range() tests which I used to verify the kernel fixes that are now in master [1]. The bounds check test depends on an xfs_io change that was merged to xfsprogs v5.1.0-rc1 (copy_range -f). The cross-device copy test checks a new functionality, so it does _notrun if copy_range return EXDEV instead of failing. Thanks, Amir.
