Since the sctp_sockaddr_entry is now RCU enabled as part of the patch to synchronize sctp_localaddr_list, it makes sense to change all handling of these entries to RCU. This includes the sctp_bind_addrs structure and it's list of bound addresses. This list is currently protected by an external rw_lock and that looks like an overkill. There are only 2 writers to the list: bind()/bindx() calls, and BH processing of ASCONF-ACK chunks. These are already seriealized via the socket lock, so they will not step on each other. These are also relatively rare, so we should be good with RCU. The readers are varied and they are easily converted to RCU. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com> Acked-by: Paul E.
