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

This patch contains some changes to related rhashtable:

- Remove check of a NULL table in rhash_table_walk
- 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.

Tom Herbert (5):
  rhashtable: Don't reset walker table in rhashtable_walk_start
  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
