Sachin Prabhu 11e31647c9 cifs: remove any preceding delimiter from prefix_path ... We currently do not check if any delimiter exists before the prefix path in cifs_compose_mount_options(). Consequently when building the devname using cifs_build_devname() we can end up with multiple delimiters separating the UNC and the prefix path. An issue was reported by the customer mounting a folder within a DFS share from a Netapp server which uses McAfee antivirus. We have narrowed down the cause to the use of double backslashes in the file name used to open the file. This was determined to be caused because of additional delimiters as a result of the bug. In addition to changes in cifs_build_devname(), we also fix cifs_parse_devname() to ignore any preceding delimiter for the prefix path. The problem was originally reported on RHEL 6 in RHEL bz 1252721. This is the upstream version of the fix. The fix was confirmed by looking at the packet capture of a DFS mount.
