====================
mptcp: Another set of miscellaneous MPTCP fixes
This is another collection of MPTCP fixes and enhancements that we have
tested in the MPTCP tree:
Patch 1 cleans up cgroup attachment for in-kernel subflow sockets.
Patches 2 and 3 make sure that deletion of advertised addresses by an
MPTCP path manager when flushing all addresses behaves similarly to the
remove-single-address operation, and adds related tests.
Patches 4 and 8 do some minor cleanup.
Patches 5-7 add MPTCP_FASTCLOSE functionality. Note that patch 6 adds MPTCP
option parsing to tcp_reset().
Patch 9 optimizes skb size for outgoing MPTCP packets.
