I could find some references to "rhashtable_insert_rehash" with grep:
/usr/src/linux/lib/rhashtable.c:int rhashtable_insert_rehash(struct
rhashtable *ht)
/usr/src/linux/lib/rhashtable.c:EXPORT_SYMBOL_GPL(rhashtable_insert_rehash);

This file is present in 3.18.11 kernel (I don't have older sources on
this laptop).
Which distribution and kernel are you using?
You are compiling 4.0 (-> 3.20) modules, so you're likely to get strange
issues if your kernel is too old.

Gabriele
