This should be the right kernel for b1_8, according to lustre/ChangeLog

This is trying to build the ldiskfs module from the ext3 sources.  It  
_should_ work, given that you have the right kernel sources, but  
clearly either the patch was changed, or something is different  
between your ext3 and what the patch expects.  This is normally just a  
simple context error.

To fix this:

cd ldiskfs/ldiskfs/linux-stage
quilt push -f
{apply include/linux/ext3_fs.h.rej to ext3_fs.h by hand}
quilt refresh
cd -

then "make" should work again.
