libsmbclient copychunk functionality was added via:
https://git.samba.org/?p=samba.git;a=commit;h=f73bcf4934be
IIRC, it was added with the intention of being used by Nautilus.
That said, I've not tried it myself, and I don't see any reference to
splice in:
https://gitlab.gnome.org/GNOME/gvfs/blob/master/daemon/gvfsbackendsmb.c
(Perhaps I'm looking in the wrong place?).
Cheers, David
