make_dead_vnode undefined in OpenBSD-2.4?

[Naomaru Itoi]

Hello Arla developers, 

I am using Arla with OpenBSD-2.2, and it is working quite well.
Thanks for your accomplishment! 

Now I am trying to install Arla-0.20 in OpenBSD-2.4 on i386, and am
having a problem.  After installing it, when I loaded xfs_mod.o like
this, 

modload -e xfs_mod -o /var/tmp/symbols -p /usr/arla/bin/xfs_makedev /usr/arla/bin/xfs_mod.o

It says symbols make_dead_vnode, xfs_stat_filesys, and
xfs_may_uninstall_filesys are not defined.  They are referenced in
xfs/bsd/xfs_vfsops-common.c and xfs/bsd/xfs_wrap-bsd.c, but are not
defined.  I thought it was weird because make_dead_vnode was defined
in xfs/bsd/xfs_vfsops.c in Arla-0.6.  

Is this a bug, or am I doing something wrong? 

Thanks.
