v5:
- merge mptcp_nl_remove_subflow() and mptcp_nl_remove_addr()

- reduce the indentation level in mptcp_pm_nl_rm_addr_received
v4:
- update mptcp_subflow_shutdown()'s args.

- add conn_list empty check.
- move anno_list to mptcp_pm_data.
- add a new patch 'mptcp: add remove subflow support'.
v3:
- fix memory leak and lock issue in v2.
- drop alist in v2.
- fix mptcp_subflow_shutdown's arguments.
- bzero remote in mptcp_pm_create_subflow_or_signal_addr.
- add more commit message.

[MPTCP][PATCH v8 mptcp-next 0/8] Add REMOVE_ADDR support
by Geliang Tang
v8:
- drop anno_list in v7.
We don't need to add a new list, conn_list is enough for the signal
address and local subflow.
- fix local_id and remote_id issues.
The RM_ADDR logic uses an address id to identify the removing
address, so we must make sure the subflow's local_id and remote_id be
set properly.
- fix mptcp_pm_nl_rm_addr_received logic issue
- update selftests
v7:
- add RM_ADDR mib
- update RM_ADDR selftests test case
v6:

[PATCH net-next] tcp: propagate MPTCP skb extensions on xmit splits
by Paolo Abeni
When the TCP stack splits a packet on the write queue, the tail
half currently lose the associated skb extensions, and will not
carry the DSM on the wire.
The above does not cause functional problems and is allowed by
the RFC, but interact badly with GRO and RX coalescing, as possible
candidates for aggregation will carry different TCP options.
This change tries to improve the MPTCP behavior, propagating the
skb estensions on split.
Additionally, we must prevent the MPTCP stack from updating the
mapping after the split occour: that will both violate the RFC and
fool the reader.
