    tipc: make resetting of links non-atomic · 598411d7
    Jon Paul Maloy authored
    In order to facilitate future improvements to the locking structure, we
    want to make resetting and establishing of links non-atomic. I.e., the
    functions tipc_node_link_up() and tipc_node_link_down() should be called
    from outside the node lock context, and grab/release the node lock
    themselves. This requires that we can freeze the link state from the
    moment it is set to RESETTING or PEER_RESET in one lock context until
    it is set to RESET or ESTABLISHING in a later context. The recently
    introduced link FSM makes this possible, so we are now ready to introduce
    the above change.
