Jeff Layton 7094564372 cifs: always do is_path_accessible check in cifs_mount ... Currently, we skip doing the is_path_accessible check in cifs_mount if there is no prefixpath. I have a report of at least one server however that allows a TREE_CONNECT to a share that has a DFS referral at its root. The reporter in this case was using a UNC that had no prefixpath, so the is_path_accessible check was not triggered and the box later hit a BUG() because we were chasing a DFS referral on the root dentry for the mount. This patch fixes this by removing the check for a zero-length prefixpath. That should make the is_path_accessible check be done in this situation and should allow the client to chase the DFS referral at mount time instead.
