Florian Westphal e1e551bc56 xfrm: policy: prepare policy_bydst hash for rcu lookups ... Since commit 56f047305d ("xfrm: add rcu grace period in xfrm_policy_destroy()") xfrm policy objects are already free'd via rcu. In order to make more places lockless (i.e. use rcu_read_lock instead of grabbing read-side of policy rwlock) we only need to: - use rcu_assign_pointer to store address of new hash table backend memory - add rcu barrier so that freeing of old memory is delayed (expansion and free happens from system workqueue, so synchronize_rcu is fine) - use rcu_dereference to fetch current address of the hash table.
