This patch moved the drop_other_suboptions check from mptcp_established_options_add_addr() into mptcp_pm_add_addr_signal(), do it under the PM lock to avoid the race between this check and mptcp_pm_add_addr_signal(). For this, added a new parameter for mptcp_pm_add_addr_signal() to get the drop_other_suboptions value. And drop the other suboptions after the option length check if drop_other_suboptions is true. Additionally, always drop the other suboption for TCP pure ack: that makes both the code simpler and the MPTCP behaviour more consistent.

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.
