Subject[PATCH 0/8] Assorted rhashtable fixes and cleanups
This series contains some bugfixes, mostly minor though one
is worthy of a stable backport I think - tagged with Fixes and Cc: stable.

Then there are improvements to walking, which have been discussed
to some degree already.
Finally a code simplification which I think is correct...



NeilBrown (8):
rhashtable: silence RCU warning in rhashtable_test.
rhashtable: remove nulls_base and related code.
rhashtable: use cmpxchg() to protect ->future_tbl.
rhashtable: fix race in nested_table_alloc()
rhashtable: remove rhashtable_walk_peek()
rhashtable: further improve stability of rhashtable_walk
rhashtable: add rhashtable_walk_prev()
rhashtable: don't hold lock on first table throughout insertion.
