Subject: [PATCH v2 net-next 0/5] rhashtable: New features in walk and bucket 

This patch contains some changes to related rhashtable:

- Above allow rhashtable_walk_start to return void
- Add a functon to peek at the next entry during a walk
- Abstract out function to compute a has for a table
- A library function to alloc a spinlocks bucket array
- Call the above function for rhashtable locks allocation

Tested: Exercised using various operations on an ILA xlat
table.

v2:
 - Apply feedback from Herbert. Don't change semantics of resize
   event reporting and -EAGAIN, just simplify API for callers that
   ignore those.
 - Add end_of_table in iter to reliably tell when the iterator has
   reached to the eno.

Tom Herbert (5):
  rhashtable: Change rhashtable_walk_start to return void
  rhashtable: Add rhastable_walk_peek
  rhashtable: abstract out function to get hash
  spinlock: Add library function to allocate spinlock buckets array
  rhashtable: Call library function alloc_bucket_locks
