Thanks for covering the patch submission and formatting guidelines, 
Matthieu.

Dymtro, it will also be important to add some 'fast open' coverage to the 
kernel self tests in this directory of the kernel source tree:

tools/testing/selftests/net/mptcp/

There's a short guide to running these tests at 
https://github.com/multipath-tcp/mptcp_net-next/wiki/Testing#kselftest


We appreciate your work to add this feature to MPTCP in the Linux kernel!
