This whole idea of cross-device copie has always been a horrible idea,
and I've been arguing against it since the patches were posted.
Ok. I'm good with this v2 as well, but need to add the fallback to
do_splice_direct()
in nfsd_copy_file_range(), because this patch breaks it.

And the commit message of v3 is better in describing the reported issue.

Thanks,
Amir.
