For 4.0.3 I replaced the two rhashtable files by current Linus version,

Are you sure the same bug happens in 3.17 too? I can certainly see
this happening after the dynamic rehashing code went in.

But in 3.17 it was doing everything under one single lock so I can't
really see how things can go wrong.
