When binding a non-abstract AF_UNIX socket it will gain a representation in the filesystem. Enable the socket infrastructure to handle idmapped mounts by passing down the user namespace of the mount the socket will be created from. If the initial user namespace is passed nothing changes so non-idmapped mounts will see identical behavior as before.

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.
