    rhashtable: Add rhashtable_free_and_destroy() · 6b6f302c
    Thomas Graf authored
    rhashtable_destroy() variant which stops rehashes, iterates over
    the table and calls a callback to release resources.
    Avoids need for nft_hash to embed rhashtable internals and allows to
    get rid of the being_destroyed flag. It also saves a 2nd mutex
    lock upon destruction.
    Also fixes an RCU lockdep splash on nft set destruction due to
    calling rht_for_each_entry_safe() without holding bucket locks.
    Open code this loop as we need know that no mutations may occur in
