Hi Zheng, this has been committed:

commit 92449b7f36aba627adc3b2f11c1184292c5e43c7
Author: Zheng Liu <wenqing.lz at taobao.com>
Date:   Tue May 14 13:25:44 2013 -0500

     In xfstest 285/286 we don't check whether the target file system
     supports seek data/hole operation or not.  Here _require_seek_data_hole
     is defined to do this work.

Thanks
