Sadly, I don't have very good tests and I was mostly using the example program from the man page under various filesystems and setups. At LPC, Darrick made it sound like he was going to work on adding vfs_copy_file_range() tests to xfstests but that probably turned into the reflink/dedupe ioctl tests.
I can try to find time to write something for xfstests if that would be useful!
