    rhashtable: Introduce rhashtable_walk_* · f2dba9c6
    Herbert Xu authored
    Some existing rhashtable users get too intimate with it by walking
    the buckets directly.  This prevents us from easily changing the
    internals of rhashtable.
    
    This patch adds the helpers rhashtable_walk_init/exit/start/next/stop
    which will replace these custom walkers.
    
    They are meant to be usable for both procfs seq_file walks as well
    as walking by a netlink dump.  The iterator structure should fit
    inside a netlink dump cb structure, with at least one element to
    spare.
