Jon Paul Maloy 5a9ee0be33 tipc: use registry when scanning sockets ... The functions tipc_port_get_ports() and tipc_port_reinit() scan over all sockets/ports to access each of them. This is done by using a dedicated linked list, 'tipc_socks' where all sockets are members. The list is in turn protected by a spinlock, 'port_list_lock', while each socket is locked by using port_lock at the moment of access. In order to reduce complexity and risk of deadlock, we want to get rid of the linked list and the accompanying spinlock. This is what we do in this commit. Instead of the linked list, we use the port registry to scan across the sockets. We also add usage of bh_lock_sock() inside the scope of port_lock in both functions, as a preparation for the complete removal of port_lock. Finally, we move the functions from port.c to socket.c, and rename them to tipc_sk_sock_show() and tipc_sk_reinit() repectively.
