Julian Anastasov 088339a57d ipvs: convert connection locking ... Convert __ip_vs_conntbl_lock_array as follows: - readers that do not modify conn lists will use RCU lock - updaters that modify lists will use spinlock_t Now for conn lookups we will use RCU read-side critical section. Without using __ip_vs_conn_get such places have access to connection fields and can dereference some pointers like pe and pe_data plus the ability to update timer expiration. If full access is required we contend for reference. We add barrier in __ip_vs_conn_put, so that other CPUs see the refcnt operation after other writes. With the introduction of ip_vs_conn_unlink() we try to reorganize ip_vs_conn_expire(), so that unhashing of connections that should stay more time is avoided, even if it is for very short time.
