Not necessarily -stable material though - this is a really light memory 
leak and only on a rare failure path, i doubt anyone noticed in 
practice.

So d508afb fixed all that needed fixing and there's nothing serious 
pending here. I've reverted all pending bits in tip:out-of-tree, so it's 
pure -git now. I rarely have to carry any NFS fixes in out-of-tree, this 
was an odd-one-out exception that fell through the cracks.
