Hello all,
Recently when I'm investigating the xfstests generic/213 generic/228 failures for cifs.
Found that fallocate can't change the cifs disk space usage. Comparing xfs fileystem,
fallocate can update space usage.
My tests is in 5.8.0-rc7+. I also file a bug for this issue.

# cat /etc/samba/smb.conf
[cifs]
path=/mnt/cifs
writeable=yes
# mount //localhost/cifs cifs -o user=root,password=redhat,cache=none,actimeo=0
# df -h cifs
Filesystem Size Used Avail Use% Mounted on
//localhost/cifs 36G 23G 13G 66% /root/cifs
# fallocate -o 0 -l 2g /root/cifs/file1
# df -h cifs
Filesystem Size Used Avail Use% Mounted on
//localhost/cifs 36G 23G 13G 66% /root/cifs
]# ls -l cifs
total 1
-rwxr-xr-x. 1 root root 2147483648 Aug 2 21:57 file1
Thanks.
