There's the nfsdcld pipe stuff, but that was supposed to have been
ripped out in 3.10. Bruce wasn't ready to do that since we didn't have
a solution to the problem of using a UMH upcall in a container.

As far as I'm concerned, we should go ahead and rip that out and worry
about the UMH in a container problem later. Bruce, any objection to
going ahead and doing that? I can respin/resend the patch to do that if
you're ready for it...
