I thought that /proc/sysvipc has the same bug as /proc/net
commit 1fde6f21d9
proc: fix /proc/net/* after setns(2)
However, it doesn't! /proc/sysvipc files do
get_ipc_ns(current->nsproxy->ipc_ns);
in their open() hook and avoid the problem.
Keep the test, maybe /proc/sysvipc will become broken someday :-\

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.
