I just mounted a network drive (Windows Server) via CIFS under 2.6.27.8, and
the sizes reported by "df" are completely incorrect:

 root@exodus:~# df -h /mnt/fsv1
 Filesystem            Size  Used Avail Use% Mounted on
 //fsv1/Users          446G -222G  667G   -  /mnt/fsv1
 root@exodus:~# df /mnt/fsv1
 Filesystem           1K-blocks      Used Available Use% Mounted on
 //fsv1/Users         467403140 -231816588 699219728   -  /mnt/fsv1
 root@exodus:~# mount | grep fsv1
 //fsv1/Users on /mnt/fsv1 type cifs (rw,mand)
 root@exodus:~#

Does anyone else see this sort of behavior with 2.6.27.8?  This worked fine
in 2.6.27.6 (we skipped 2.6.27.7)...

Ideas?
Well, lets cc the relevant people so your report isn't lost in the noise.
FWIW, it seems to be related to this one: http://lkml.org/lkml/2008/12/8/7

Thanks,
Rafael

There were several cifs updates in .8 but AFAIU none in .7.

Holger's report is about the userland SMB/CIFS server, while Denis's is
about kernelspace client code.  They look like separate issues to me.

I tried it on both i386 and x86_64 and had no problems. Is this client
non-x86 by any chance?
