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.
