Allow nfs_copy_file_range to copy across devices. NFSv4.2 inter server to server copy always copies across devices, and NFSv4.2 intra server to server copy can copy across devices on the same server. If a file system's fileoperations copy_file_range operation prohibits cross-device copies, fall back to do_splice_direct. This is needed for nfsd_copy_file_range() which is called by the inter server to server destination server acting as an NFS client, and reading the file from the source server.

What has happened to the patch? We unwittingly used copy_file_range in the glibc test suite, without realizing that it does not support cross-device copies.
Thanks, Florian
