[ Upstream commit 724b00c12957973656d312dce2a110c75ae2c680 ]
OPTIONS_MPTCP_MPC is a combination of three flags.
It would be better to be strict about testing what
flag is expected, at least for code readability.
mptcp_parse_option() already makes the distinction.
- subflow_check_req() should use OPTION_MPTCP_MPC_SYN.
- mptcp_subflow_init_cookie_req() should use OPTION_MPTCP_MPC_ACK.
- subflow_finish_connect() should use OPTION_MPTCP_MPC_SYNACK
- subflow_syn_recv_sock should use OPTION_MPTCP_MPC_ACK

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
