Subject: [PATCH net-next 0/5] mptcp: Miscellaneous fixes

Here are five changes we've collected and tested in the mptcp-tree:

Patch 1 changes handling of the MPTCP-level snd_next value during the
recovery phase after a subflow link failure.

Patches 2 and 3 are some small refactoring changes to replace some
open-coded bits.

Patch 4 removes an unused field in struct mptcp_sock.

Patch 5 restarts the MPTCP retransmit timer when there is
not-yet-transmitted data to send and all previously sent data has been
acknowledged. This prevents some sending stalls.

Florian Westphal (3):
  mptcp: do not shrink snd_nxt when recovering
  mptcp: remove tx_pending_data
  mptcp: re-arm retransmit timer if data is pending

Geliang Tang (1):
  mptcp: use OPTIONS_MPTCP_MPC

Paolo Abeni (1):
  mptcp: use lockdep_assert_held_once() instead of open-coding it
