copy_file_range on NFSv4.2 requires that src offset and dest offset are aligned with server blocksize. So does copy count, except that after this copy, we'll reach the EOF. See Linux commit 811b7b85. ltp/fsx.c tests copy_file_range on random offset with random size by default. This makes these tests get EINVAL on NFS.
