Hello Namjae et al.

With the latest ksmbd from the next branch I have an issue with wife's Wind=
ows=20
10 laptop while copying/removing files from the network share. On her clien=
t it=20
looks like copy operation (server -> laptop) reaches 99% and then stalls, a=
nd=20
on the server side there's this in the kernel log:

```
ksmbd: Unsupported addition info: 0xf)
ksmbd: Unsupported addition info: 0x20)
```

repeated multiple times. I must note that in fact the file gets copied to h=
er=20
laptop, but Windows copy dialog just hangs.

Any idea what it could be and how to avoid it? This also happened before (I=
'm=20
a pretty early ksmbd adopter), but I'm reporting it just now because I na=
=EFvely=20
hoped it would be fixed automagically :). This never happened to me with=20
userspace Samba though.

This is my smb.conf:

```
[global]
workgroup =3D KANAPKA
server string =3D ksmbd server %v
netbios name =3D defiant
valid users =3D __guest

[Shared]
valid users =3D __guest
path =3D /mnt/shared
force user =3D _shared
force group =3D _shared
browsable =3D no
writeable =3D yes
veto files =3D /lost+found/
```

Appreciate your time and looking forward to your response.

Thanks.
