Yes. My prefered mid-term solution would to simply lift that code from
XFS (where it's nicely isolated and all code is prefixed with hack_) to
nfsd so that local users don't aren't penalized for this.
OCFS2 also ran into this lately, so someone at Oracle might already
be working on it. And ubifs will also run into it once it gets nfs
serving support..
