====================
rhashtable: Handle table allocation failure during insertion

v2 -

Added Ack to patch 2.
Fixed RCU annotation in code path executed by rehasher by using
rht_dereference_bucket.

v1 -

This series tackles the problem of table allocation failures during
insertion.  The issue is that we cannot vmalloc during insertion.
This series deals with this by introducing nested tables.

The first two patches removes manual hash table walks which cannot
work on a nested table.

The final patch introduces nested tables.

I've tested this with test_rhashtable and it appears to work.
