Converts a manta.info() into an fs.Stats object It is critical that the dev and ino values are always the same for the same object but particularly an NFS mount. NFS clients get ther fsid and fileid from these values and will consider the mount point stale if they vary.
function mantaToStats(_path, info) {
    assert.string(_path, 'path');
    assert.object(info, 'info');

    var stats = new fs.Stats();
    stats.dev = hash(path.dirname(_path));
    stats.ino = hash(_path);
    if (info.extension === 'directory') {
        stats.nlink = parseInt(info.headers['result-set-size'], 10);
        stats.isFile = _false;
        stats.isDirectory = _true;
        stats.mode = 0755;
        stats.size = 0;
        stats.mtime = new Date(info.last_modified);
    } else {
        stats.nlink = 1;
        stats.isFile = _true;
        stats.isDirectory = _false;
        stats.mode = 0644;
        stats.size = info.size;
        stats.mtime = new Date(info.headers['last-modified']);
    }
    stats.uid = nobody_uid;
    stats.gid = nobody_gid;
    stats.rdev = 0;
    stats.atime = new Date();
    stats.ctime = stats.mtime;

    stats.isBlockDevice = _false;
    stats.isCharacterDevice = _false;
    stats.isSymbolicLink = _false;
    stats.isFIFO = _false;
    stats.isSocket = _false;

    stats._cacheFile = stats._cacheFile || info._cacheFile;
    stats._fhandle = stats._fhandle || info._fhandle;
    stats._manta = info;
    stats._path = _path;

    return (stats);
