[PATCH mptcp-next v4 0/4] MP_FAIL echo and retrans

[Geliang Tang <geliang.tang@suse.com>]

v4:
 - start and stop sk_timer instead of setting and clearing msk->flags.
 - add a new patch.

v3:
 - use msk->sk_timer and a msk->flags bit.
 - use READ_ONCE/WRITE_ONCE for subflow->mp_fail_response_expect.
 - update selftest.

v2:
 - don't clear mp_fail_response_expect flag.
 - add a helper mp_fail_response_expect_subflow to get the subflow,
   instead of using msk->first.
 - add locks as Mat suggested.
 - add a selftest.

Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/261
