Simple: please, *please* hold back until we have atomic_open mess sorted
out.  I'm fucking sick and tired of playing whack-a-mole in that area -
for nearly three years by now; we fortunately are very close to getting
this shit done right - the main remaining obstacle is ->d_revalidate()
abuse by NFS and I seriously hope to get it over and done with in a week or so.
Once that is done and the damn thing is in #for-next, I'll ping you, dhowells
and probably aufs folks to start sorting this out, so that we would have that
finished before 3.2 opens.
