Subject: [PATCH net-next 0/5] mptcp: allow privileged operations from user ns & cleanup

This series allows privileged Netlink operations from user namespaces. When a
non-root user configures MPTCP endpoints, the memory allocation is now accounted
to this user. See patches 4 and 5.

Apart from that, there are some cleanup:

 - Patch 1 adds a macro to improve code readability

 - Patch 2 regroups similar checks all together

 - Patch 3 uses an explicit boolean instead of a counter to do one more check

Geliang Tang (2):
  selftests: mptcp: move prefix tests of addr_nr_ns2 together
  mptcp: add do_check_data_fin to replace copied

Matthieu Baerts (1):
  mptcp: add mptcp_for_each_subflow_safe helper

Thomas Haller (2):
  mptcp: allow privileged operations from user namespaces
  mptcp: account memory allocation in mptcp_nl_cmd_add_addr() to user
