(or others except MPTCP_INFO of course) and then check mptcp_subflow_data->num_subflows to get the total amount of subflows. This patch adds a new counter mptcpi_subflows_total in mptcpi_flags to store the total amount of subflows, including the initial one. A new helper __mptcp_has_initial_subflow() is added to check whether the initial subflow has been removed or not. With this helper, we can then compute the total amount of subflows from mptcp_info by doing something like: mptcpi_subflows_total = mptcpi_subflows + __mptcp_has_initial_subflow(msk).
