Currently, different NFS clients can share the same DS connections, even when they are in different net namespaces. If a containerized client creates a DS connection, another container can find and use it. When the first client exits, the connection will close which can lead to stalls in other clients. Add a net namespace pointer to struct nfs4_pnfs_ds, and compare those value to the caller's netns in _data_server_lookup_locked() when searching for a nfs4_pnfs_ds to match.

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.
