commit ca6e55a703ca2894611bb5c5bca8bfd2290fd91e upstream.
The ID 0 is specific per MPTCP connections. The per netns entries cannot
have this special ID 0 then.
But that's different for the userspace PM where the entries are per
connection, they can then use this special ID 0.

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.
