Hi thank you for your advice. I replace the line, REQ_UNPLUG, with your patch, BIO_RW_UNPLUG in segbuf.c in SL6's kernel srpm archive. make is done successfully like 2.6.32.27's case (see my last post), and kernel panics like 2.6.32.27's case when unmounting the nilfs2 partition... i rebuilt the nilfs2 partition again after replacing the nilfs2.ko module and modprobe it. thanks.
