99ae7dc439In ovl_parse_param_split_lowerdirs() a backslash consumes the character that follows it. When the backslash is the last character of the lowerdir value, it consumes the NUL terminator: the loop exits normally and the backslash is kept in the output, so the lowerdir is passed downstream with a trailing backslash and the mount fails later with a confusing ENOENT from path lookup. A trailing unescaped backslash escapes nothing, so reject it with EINVAL.
