The proposed patch set is the linux client AND linux server. We need removal of the VFS cross-device check on both side (client and destination server) to make the server-to-server copy work. On the server side, we also call vfs_copy_file_range() that (when check is removed) ends up reading from the NFS source file and writing to the local file system.
