I've updated Gvfs to version 1.30.1.1-1 (Debian Testing) and I am now
able to copy directory with files inside.

However the copy doesn't seem to be done server-side. And especially
the copy doesn't seem to be done instantaneously (like what we should
expect from a copy with BTRFS reflink).

Perhaps I am misunderstanding something ?

I thought that Gvfs would use my smbclient (v4.4.6) and automatically
send the FSCTL_SRV_COPYCHUNK which would be interpreted as
BTRFS_IOC_CLONE_RANGE by the samba server (v4.2.10).

Connection manually through smbclient and issueing 'scopy' instructions
works (instantaneous copy) so the problem doesn't seem to be on the
server.

Link to the log.smbd, where I try to copy one directory:

Thanks for the help !
