The struct member "must_fail" of network_helper_opts() is only used in cgroup_v1v2 tests, it makes sense to drop it from network_helper_opts. Return value (fd) of connect_to_fd_opts() and the expect errno (EPERM) can be checked in cgroup_v1v2.c directly, no need to check them in connect_fd_to_addr() in network_helpers.c. This also makes connect_fd_to_addr() function useless. It can be replaced by connect().

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 reStructuredText 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.
