so "mount.cifs ///server/share /some_directory"?

So, a *nix machine exports a directory through its samba daemon and
another *nix machine mounts it with mount.cifs?

Here, in what filesystem are you? Is this a filesystem that's mounted
with mount.cifs?

Nope, over a CIFS (the name of the protocol used by Windows and
Samba...and mount.cifs...and the cifs kernel module) share mounted
with mount.cifs.....from my understanding.

What happens if the remote directory is a Windows share?

I suspect this to be a problem in the cifs module of the kernel.
