    [patch 3/3] OCFS2 Configurable timeouts - Protocol changes · 828ae6af

    Modify the OCFS2 handshake to ensure essential timeouts are configured
    identically on all nodes.
    
    Only allow changes when there are no connected peers
    
    Improves the logic in o2net_advance_rx() which broke now that
    sizeof(struct o2net_handshake) is greater than sizeof(struct o2net_msg)
    
    Included is the field for userspace-heartbeat timeout to avoid the need for
    further protocol changes.
    
    Uses a global spinlock to ensure the decisions to update configfs entries
    are made on the correct value.  The region covered by the spinlock when
    incrementing the counter is much larger as this is the more critical case.
