    rhashtable: Convert bucket iterators to take table and index · 88d6ed15
    Thomas Graf authored
    This patch is in preparation to introduce per bucket spinlocks. It
    extends all iterator macros to take the bucket table and bucket
    index. It also introduces a new rht_dereference_bucket() to
    handle protected accesses to buckets.
    
    It introduces a barrier() to the RCU iterators to the prevent
    the compiler from caching the first element.
    
    The lockdep verifier is introduced as stub which always succeeds
    and properly implement in the next patch when the locks are
    introduced.
