This series makes the classifier use OVS-RCU and thus makes classifier
lookups lockless. No performance measurements have been made yet.
Patch 6 ("Use cmap.") has been previously reviewed.
Jarno Rajahalme (12):
dpif-netdev: Use cmap instead of hmap.
ovs-atomic: Use memory_order_relaxed for ovs_refcount.
lib/ovs-atomic: Add atomic compare_exchange.
ofproto-dpif: Use ovs_refcount_try_ref().
lib/classifier: Remove unused typedef cls_cb_func.
lib/classifier: Use cmap.
lib/classifier: Simplify iteration with C99 declaration.
lib/ovs-rcu: Export ovsrcu_synchronize().
lib/classifier: Stylistic change.
lib/classifier: Use internal mutex.
lib/classifier: RCUify prefix trie code.
lib/classifier: Lockless lookups.
