From: "Paulo Alcantara (SUSE)" <pc@cjr.nz>
[ Upstream commit 154255233830e1e4dd0d99ac929a5dce588c0b81 ]
Ensure that full_path is an UNC path that contains '\\' as delimiter, which is required by cifs_build_devname().
The build_path_from_dentry_optional_prefix() function may return a path with '/' as delimiter when using SMB1 UNIX extensions, for example.
