Subject: [35/90] cifs: convert prefixpath delimiters in

3.0-stable review patch.  If anyone has any objections, please let us know.

------------------
 cifs_build_path_to_root

From: Jeff Layton <jlayton@...hat.com>

commit f9e8c45002cacad536b338dfa9e910e341a49c31 upstream.

Regression from 2.6.39...

The delimiters in the prefixpath are not being converted based on
whether posix paths are in effect. Fixes:
