linux speaks v3, but it's a compile-in option for the kernel or
module that's not enabled by default iirc.  The configs you want are

CONFIG_NFS_V3=y (or 'm')
CONFIG_NFS_V3=y
CONFIG_NFSD=y (or 'm')
CONFIG_NFSD_V3=y

I was just looking into xFS the other day, and unless I was on the wrong
site (it was a link off the berkeley NOW project), it looks like
it's neither stable or actively maintained (last update, 1997).  Is
there somewhere else that has a more recent version?
