Hi Dave,

Thanks for review.  I guess that you metioned this patch, right?
  [PATCH] xfstests: automatically add -F to xfs_io on non-xfs

But I couldn't find it in xfstests tree.  Has it been applied into the
tree?  Or maybe I use a wrong tree to generate my patch.  I clone the
tree from here:
  git://oss.sgi.com/xfs/cmds/xfstests

Is that right?  Or maybe I need to apply Eric's patch manually and
rebase my patch?

Good catch!  Fix it soon.

Thanks,
                                                - Zheng
